* 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! ;-)).

I "ported" the region implementation from XOrg to work on BRegion data.
This resulted in pretty much the same code structure as before, with
RegionSupport.cpp containing the messy details. Only now it _is_ really messy
from a code beauty point of view. I didn't exactly feel like cleaning it
up right now... but I guess I will have to.
So what does this mean - our BRegion implementation was very slow (no offense!),
and on top of that it scaled very badly with more and more rects. The new
implementation seems to be on par with the very fast R5 implementation and
the data looks exactly the same too. BRegion is very performance critical
for the app_server, and I cannot wait to try this on my slow computer...
Some changes are noteworthy: The right and bottom coordinates of
BRegion internal data are now exclusive! I inherited that from the
XOrg implementation and didn't feel like changing the code, seeing it
is probably tested quite well. The conversion is handled transparently.
Secondly, constructing a BRegion with just one rect is not invoking
malloc anymore for the member data, this makes it much more efficient
to use temporary BRegions with just one rect, both externally and internally
in the BRegion implementation.

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.

with the same size as the class is defined.
* 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
supplied default value, if the field element doesn't exist.
* Added also handy Set*() methods setting the value of first element of
a field, i.e. adding it, if it didn't exist before, otherwise
replacing the old value. Only for fixed size types.
* Moved _FindType() inline template method into the header.
* Made the source file fit for use in the boot loader. If the macro
KMESSAGE_CONTAINER_ONLY is defined, the message sending/receiving part
is omitted.

BDirectory without declaring it first. Since that's an actual bug, I made the
changes in the Haiku headers, and copied them back to the build headers.

* Also ported over the new MessageAdapter class
* Removed old BMessage implementation prototypes that apparently were left in the private folder
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21515 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed r5_message.cpp and dano_message.cpp accordingly
* Also moved out KMessage handling from Message.cpp to MessageAdapter.cpp
* Fixed some minor style issues in Message.cpp

* _WindowAt() and _CountWindows() now have an individual version of that
code which should be magnitudes faster.
* _WindowQuitLoop() no longer handles hidden windows specially - instead,
it now walks the window list in the correct direction which should fix
the issues.
* Also, it now uses WindowAt() and thus has an up-to-date view of the
window list (it will no longer ignore new windows).
* And finally, it will no longer dereference an unsafe pointer (for
BWindow::IsFilePanel()).

* BMailSettings::StatusWindowFrame() now returns some useful defaults.
* Minor cleanup.
* The MDR kit needs some serious overhaul before it can be part of R1.

* Added a TRACE_S3SAVAGE macro that turns on debug output - should be set conditionally
if DEBUG is defined (see DriverInterface.h), but is currently always on, as requested
by Gerald.
* Some minor style fixes.

* vm_copy_on_write_area() now does no longer overwrite the ref_count, but keeps
it's reference to the cache until it has unlocked it.
* It now also locks its reference from the start, preventing any other thread
to interfere.
* vm_cache_remove_consumer() now detects if it has to remove a foreign busy
page itself in order to preserve a mapped page.
* vm_soft_fault() now keeps a reference to the cache that owns the page to be
mapped until it has actually mapped it.
* vm_unmap_pages() removed the mappings of all pages of the area instead of only
those that are within the requested range.
* Kept (disabled) debug output for convenience.

Disabled by default, but all kernel devs are *highly* recommended to turn them on for your builds and see if it trips anything, and then fix it.

* Reworked the internal layout. _ValidateLayoutData() computes and caches the
layout related data and all other methods just use those values. Now, in
layout-aware mode the class should properly work not only when using the
layout items. And when using layout items, the class does actually do
internal layout; it was basically good luck that it worked in the tests,
before. Vertical resizing is supported, too.
* We do a few mean tricks to get the probably mostly preferred layout behavior:
By default our own explicit max width and that of the menu bar layout item is
set to unlimited and the horizontal menu bar alignment to left aligned. This
allows to horizontally resize a BMenuField beyond its preferred size,
although both label and menu bar have a limited max width. The user can, of
course, override those explicit sizes/alignments to get a different behavior,
if desired.
* Fixed invalidation in SetDivider(). When having the focus, the left and top
border of the blue frame were not invalidated.
* The label is no longer drawn at vertical position font ascent + descent
+ leading + 2 (not sure how this calculation was supposed to work), but
vertically centers the label around the ascent. With big fonts the label is
shown a bit too far to the bottom. Not sure how to fix this in a generic way.

the maximum width. The latter supports unlimited maximum width. The
_BMCMenuBar_ draws fine when resized wider than its min/preferred width, but
not the complete "button" area will cause the menu to open when being pressed.
