reduce the amount of code generated each time the template is
instantiated.

* Removed the ref_count from vm_areas. You now always need to have the address
space locked (read or write, depending on what you do) when dealing with
areas.
* Added helper classes for locking the address space: AddressSpace{Read|Write}Locker,
and MultiAddressSpaceLocker which can lock several spaces at once and makes
sure no dead locks can happen.
* resize_area() is now using the MultiAddressSpaceLocker instead of no locking
at all; ie. it should now be safely to use.
* Disabled transfer_area() for now; it will be changed to work like an atomic
clone_area()/delete_area(), that is, it will hand out a new ID for the
transfered area.

* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
read/write locking to the list of cache entries (fonts) as well as
read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
glyphs along the baseline.
It handles the locking for getting the font cache entries.
It works by giving it a template class GlyphConsumer which does the
actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
is the same, which of course it isn't, hence the two separate functions...
AsGlyphs just gets the bounding box of each glyph in a string, not treating
the string as an actual word
AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning

* Simplified the notification framework: removed the updater stuff completely;
it was only there to account for some peculiarities of the node monitor which
we now solved differently.
* NotificationListener no longer includes a doubly linked list link for convenience;
it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
longer possible to just remove some flags separately, just to stop listening
completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
couldn't do a lot with the KMessage in the kernel without using a private API.
Now you will have to use the (private) notification manager to use the node monitor
from inside the kernel. At a later point, we might introduce a public API for that,
too.

therefore, we could remove the ugly defines from KMessage again, and compile it
with KMESSAGE_CONTAINER_ONLY.
* Added KMessage::SetDeliveryInfo() to be able to send messages with a correct

a negative value for the parameter, but override it when passing in a valid

* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
compile with _LOADER_MODE defined.

of the active ViewLayer is now always mirrored in the Painter instance
of a ServerWindow, so that it doesn't need to be synced on every drawing
command, this was previously incomplete for font handling
* removed the DrawState parameter from all the DrawingEngine functions
* adjusted ServerWindow and ServerPicture accordingly
* made sure that string related functions used by non-drawing related
parts (ServerApp, Decorator) don't interfere with the current drawing
state
* moved AS_SYNC handling from _DispatchViewMessage to _DispatchMessage,
it is actually a window message and doesn't require fCurrentLayer to
be valid
* fixed bug #1300, fCurrentLayer was not updated when a ViewLayer was
deleted by client request which happened to be fCurrentLayer (I am now
handling it so that the parent becomes the current layer, could be
wrong)
* AGGTextRenderer is no longer using it's own scanline, which should save
a few bytes RAM, the Painter already had such an object
* StringWidth() in AGGTextRenderer is now taking the escapement_delta into
account
* Painter::StrokeLine() doesn't need to check the clipping as much, since
that is already done in DrawingEngine
* if a ServerWindow message is not handled because fCurrentLayer is NULL,
a reply is sent in case the messages needs it (client window could
freeze otherwise, waiting for the reply for ever)
* removed unused AS_SET_FONT and AS_SET_FONT_SIZE
* added automatic RGBColor -> rgb_color conversion to RGBColor.h

* More conditional debug code (wrt page transitions between caches).
* Replaced debugger command cache_chain by a nicer cache_tree.
* While handling a soft fault: When we temporarily unlock a cache, it
can theoretically become busy. One such occurrence is now handled
properly, two more panic() ATM, though should be fixed.
* When merging caches, we do now always replace a dummy page in the
upper cache, not only when the concurrent page fault is a read fault.
This prevents a page from the lower (to be discarded) cache from still
remaining mapped (causing a panic).
* When merging caches and replacing a dummy page, we were trying to
remove the dummy page from the wrong cache (causing a panic).
The Haiku kernel seems now to run shockingly stable. ATM, we have more
than two hours uptime of a system booted and running over network. We
didn't manage to get it down by fully building Pe, downloading, unzipping,
and playing with various stuff. Someone should finally fix all those app
server drawing bugs, though (hint, hint! ;-)).

stack hungry and would previously hit the stack limit and thus cause a
double fault. Hopefully we'll be able to reduce the stack foot print at
some time.
PXE boot does now fully work.

* Images preloaded by the boot loader had to be modules to be of any use
to the kernel. Extended the mechanism so that any images not accepted
by the module code would later be tried to be added as drivers by the
devfs. This is a little hacky ATM, since the devfs manages the drivers
using a hash map keyed by the drivers inode ID, which those drivers
obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
doesn't implement the former (all old-style drivers), thus making it
possible to BFS, which uses the file cache which in turn requires
read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
more flexibly be extended and deals more gracefully with
arbitrarily-size data. The disk_identifier structure still exists,
though. It is added as message field in cases where needed (non net
boot). Moved the boot_drive_number field of the bios_ia32 platform
specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
initialization code into the stage 2 loader, which can now be loaded
directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
does no longer use the RemoteDisk protocol (it could actually be
removed from the boot loader). It also parses the DHCP options in the
DHCPACK packet provided by PXE and extracts the root path to be
mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
added support for network boot. In this case the net stack is
initialized and the network interface the boot loader used is brought
up and configured. Since NBD and RemoteDisk are our only options for
net boot (and those aren't really configurable dynamically) ATM, the
the boot device is found automatically by the disk device manager.
Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

* The SetTo() methods do now accept an unspecified (negative) bufferSize
in case of being told to initialize from the given buffer.
* Added handy Get*() methods returning a field element value or a

* Added also handy Set*() methods setting the value of first element of

Adding this required adding some new Jam rules to deal with this shared source
directory and headers. I had some fun figuring this out. Despite writing
articles about Jam in the Haiku newsletter a few years ago I still find Jam to
be a PITA at times.
But my solution seems to work pretty well. Basically you just call the rule
UseSharedSource and pass the name of the shared source file you want to use.
This rule sets up the header directories and the right Jam variables for the
source file. You then add the source file to the source list in the Application
rule like any other source file.
I also made the authors list sent to the about window constructor null
terminated instead of passing the size of the array, as suggested by Hugo.

realized that calling it a window may not be strictly correct since it isn't a
decendent of BWindow, but just uses a BAlert. Oh well, it can be changed if
need be.
I'm also checking in the first use of it, in ShowImage. Since ShowImage can
still be compiled for R5 I've added a #ifdef around the new BAboutWindow
related code.
I'm open for suggestions for the interface for this class, well mostly the
constructor. I'm not a big fan of having to specify the number of authors.
For now I'm making the header private, but I don't think it would be a big deal
to expose it publically.

The lower scroller wasn't shown anymore for some reason, and this commit also fixes this problem.

- Properly flag sockets using non-blocking connects() when in SYN SENT.
- and when in LISTEN, we should use the socket's connection queue size.

- Introduced public net_device_monitor.
- Changed the link protocol to maintain a lock per instance instead of inside the FIFO. Now all of the link instance data is protected.
- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.

- changed the socket module to use thew new RECEIVE/SEND in all forms of recv() and send()
- changed libnetwork to use the new RECEIVE/SEND
- remove transfer_args processing from strace since the structure was removed

* The device interface list now uses class DoublyLinkedList instead of struct list.
* Implemented SIOC[SG]IFMEDIA for setting (not supported by any device yet), and
retrieving the device media information.
* Fixed a locking bug in list_domain_interfaces().
* Added new stack function device_link_changed() that should be called in case the
link state (media) changed.
* The ethernet device module now spawns a thread and will periodically check the media
state of all ethernet devices that support this (if any).
* Minor cleanup.

it might also be a good idea to change the constants to better match the usual
style.
* Added a BSD-style if_media.h.
* Added interface flags IFF_LINK, IFF_AUTO_CONFIGURED, and IFF_CONFIGURING. The
former will be set automatically by the stack, the rest will be set by the
net_server depending on the current state.

rewind_query() -- are passed to the userland. get_vnode_name() has an
emulation in userland, in case the client FS doesn't implement it.

in.
* New debugger command "find_page", which searches all page queues to
find out, which one a page is actually in.
* Solved nasty race condition between the page scrubber and
vm_page_allocate_page_run(): The page scrubber didn't mark the pages
it was processing busy, so that vm_page_allocate_page_run() could claim
them in the meantime. They would end up in the clear pages queue,
although being assigned to a cache at the same time. This should
finally solve bug #1056.

* Removed headers/private/shared/ObjectLocker.h and replaced all uses of
BObjectLocker by AutoLocker.

* Added a comment to vm_remove_all_page_mappings() that shows that we need to
change the mapping spinlock into a mutex.
* Pointed out some potential problems in the code.
* Added vm_page_at_index(), vm_clear_map_activation(), and vm_test_map_activation()
in preparation of the page scanner rewrite.

possibility to initialize the AutoLocker without locking the object even
if it is unlocked yet. Especially in loops Lock()/Unlock() come handy
when an otherwise constantly hold lock needs to be unlocked for a short
time.
I suppose we should move the kernel utils AutoLocker implementation
to headers/private/shared, and drop the less powerful ObjectLocker.

{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.
We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

header.

that points to both, the page and the area the page is in. This will allow a page
scanner to steal unused pages when necessary.
* The locking is currently done with a spinlock which we might want to have another
look at one day.
* dump_page() and dump_area_struct() now dump the page mappings as well.

avoid passing requests to the userland that can't be serviced anyway.

add-ons accordingly and removed the syscall.
* Removed send_notification().
* Reimplemented notify_listener(). It used the unimplemented
send_notification(). Now it has a chance to work. Note that
notify_listener() is obsolete. I would already have removed it, if
there weren't lots of FS implementations still using it (Hint!).

change.
* The new notification functions are used instead of send_notification()
and notify_listener() now. Mapped them in the BeOS kernel emulation
accordingly. RamFS node monitoring seems to work now.

Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.
Note: some functions of PicturePlayer don't appear to be implented by PictureDataWriter,

to B_FULL_LOCK.
* vm_clone_area() now respects the source area's wiring and inherits it. This
should fix bug #1055.
* vm_cache::type is now duplicated in vm_area::cache_type - this allows looking
it up without having to lock a vm_cache_ref; this also solves a locking bug
in vm_unmap_pages() in this regard.

Basically, there was a pretty subtle race between the cpus in main where if the main cpu released the AP cpus and then before the AP cpus had a chance to run the boot cpu started creating the main thread (which causes smp ici messages to be created) the system would livelock, where the boot cpu waited forever for the AP cpu to acknowledge the ICI (for a TLB flush when creating the kernel stack).
Added smp_cpu_rendezvous(), used to synchronize all the cpus to a particular point, and used it a few times in main().
While i was at it i fixed another race that'll probably never happen, but what the hey. Make sure the kernel args are copied into kernel space by the main cpu before letting any other ones use it.

* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.

old interface is completely done in userland ATM.
It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).
