job alright.

* Implement color palette generation for the boot splash images in the
generate_boot_screen build tool. Only 4-bit screen support is missing now.
* Adopted images.h with the new results from generate_boot_screen.
This should fix black boot screens for graphics cards that don't support
true color modes for the native resolution. I've tried to find the ticket,
#2177 almost looks like the one, but it looks more like the mode is out
of range if I understand the ticket right.
Thanks a lot, David, and sorry it took so very long to apply your patch!

Powel. The functionality was written by Jeff Prosise and Davide Pizzolato and
has been cleaned up and adopted to the Haiku coding style by David Powell and
myself. The class can perform a color quantization for generating the optimal
color index palette (with given maximum size) from a given RGBA image.

referencing iframe registers. Their prefix is "$". E.g. "$eax" refers to
the eax register of the current iframe. The features cooperates with the
"in_context" command, i.e. "in_context 92 $eip = 0" will set the eip
register of thread 92 to 0 (thus sealing its fate ;-)).

due to alignment padding before.
* Reorganized merging of caches a bit. Renamed MergeStore() to Merge()
and moved some more functionality into it. The method also moves the
pages from source to consumer, now. This is necessary, since
VMAnonymousCache needs to consider both physical pages and swap pages
at the same time. Before we first moved the physical pages and the
swap pages later, which was broken for two reasons: (1) A swap page in
the consumer cache shadows a physical page of the source cache, which
we ignored. (2) A source cache's physical page that also had a swap
page would lose the latter in the process when moved to the consumer
cache, i.e. if the page was not marked modified, it could be stolen
and its data would be lost.
These changes improve the situation when building Haiku with 256 MB RAM
in that jam doesn't crash anymore, but in my test the system became
totally unusable after about an hour or 7000 targets (GUI froze). For
some reason it didn't manage to free pages anymore although swapping
heavily.

* The "in_context" command does now set the currently debugged thread
respectively.

debugger and added respective getter/setter methods
debug_{get,set}_debugged_thread(). By default the currently debugged
thread is the thread that dropped into the kernel debugger, but commands
like "in_context" can change it.

mainly supposed to be used for resizing allocations asynchrounously.

* When the new flag CREATE_AREA_DONT_WAIT is specified, the functions
don't wait for memory or pages to become available. They fail
immediately instead.

of free objects an object cache should try to have ready. If the number
of free objects drops below the threshold, a new urgent priority thread
is asked to asynchronously resize the object cache (pretty similar to
the heap grower thread). Such a mechanism is necessary for code paths
that are supposed to free pages, but may need memory themselves (like
the swap support).

given only the allocation for the specified heap are considered.

be passed on to the IORequest. Most relevantly physical pages can now
be written directly by passing B_PHYSICAL_IO_REQUEST.
* Added VMCache::WriteAsync() which is supposed to write pages
asynchronously. The base class version version falls back to the
synchronous Write(). Only VMVnodeCache implements WriteAsync() ATM,
VMAnonymousCache (swap support) still has to be adjusted accordingly.
* write_page() doesn't need to map the page anymore as it can write the
physical page directly.
* Modified the page writer to write pages asynchronously. This shouldn't
have any noticeable effect yet. It will though as soon as the I/O
scheduler reorders I/O operations.

- B_GET_ICON_NAME: returns the name of an icon. This will then be read from
a predefined location on disk (not yet implemented). This would also allow
to add specifiers like "-boot", or "-fat|bfs|ntfs|...", and have special
icons for those.
- B_GET_VECTOR_ICON: retrieves the vector icon of a device, if any.
* get_device_icon(BBitmap*, ...) now supports other color spaces than B_CMAP8.
* Added get_device_icon(), BPartition::GetIcon(), and BVolume::GetIcon()
variants that can also retrieve the icon data directly (like
BNodeInfo::GetIcon()).
* Reenabled the previous BPartition::GetIcon(), based on a patch by
Justin O'Dell - this fixes#1391.
* Tracker's MountMenu class now uses B_RGBA32 icons, instead of B_CMAP8.
* Added vector icon to scsi_disk, and scsi_cd. The former doesn't have any
special removable icon, though.
* Header cleanup, added/updated license, whitespace cleanup.
* Marked deprecated/obsolete driver ioctls in Drivers.h.
* Removed OpenBeOS namespace in the headers I touched that still had them.

Ingo suggestions: instead of having one global sem_undo list,
we now have two local list, one per semaphore set and one per team
which is held in its xsi_sem_context structure, along with a mutex.
A mutex has also been added to the semaphore set class in order to
protect the local list, but also in order to (hopefully) improve
concurrency.

currently points to /etc for the system, and dedicated "data" directories
for common/user (the system directory should get a dedicated "data", too,
though).
* Added B_USER_CACHE_DIRECTORY (in config/cache).
* These additions were discussed some years ago, but I just had a good reason
to use them :-)
* Coding style cleanup.

wait_for_timer() function.
* Moved the internal Fifo class into utility.cpp - we should probably just
remove it again.
* Fixed uninit_timers() so that it would even work in combination with the
timer thread if there are timers left to be scheduled.
* Minor cleanup.

our dma_restrictions structure (but we're using blocks instead of bytes,
since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.

heap_class object now. Removed unused heap_allocator::heap_class.
* Made heap_class, heap_create_allocator(), heap_memalign(), heap_free()
public, so that a specialized allocator can be used elsewhere in the
kernel.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26965 a95241bf-73f2-0310-859d-f6bbb57e9c96

return 0x4.

get_window_order() will retrieve the application respectively window order
on the selected workspace.
* Moved private BeOS compatible functions (as used by the Deskbar) into the
private WindowInfo.h header.
* Whitespace cleanup.

* The global BPathMonitor looper is now always used, no more optional looper
and no more BApplication looper usage. This way we know how the looper behaves
and PathHandler::Quit() can be synchronous. In the end, the bug I was
observing was not caused by the previous asynchronous node monitor stopping,
but this should be safer anyways. When BPathMonitor::StopWatching() returns,
you have really stopped watching and not some time later.
* Introduced "FileEntry" which is an entry_ref plus node id. This is now used
instead of the node_ref for the "watched files set". The whole point
is to really be able to add the "path" field to the B_PATH_MONITOR message.
Previously, the initial path that was passed to StartWatching() was added,
regardless if the message was for an entry somewhere down the hierarchy when
watching recursively. The downside of the new method is that it uses a lot
more RAM per entry. Another option would be to store the node id of the parent
directory and iterate the directory always when in need to construct the path.
* Watching a folder recursively now really adds all the existing subfolders
as well as all the files if not watching for folders only. The tests for the
old implementation only tested what happens when the watched folder was newly
created and then subfolders were created. Those where already added by the
code. Now it also adds the subfolders of folder that appear in a watched
folder.
TODO: Remove folders and files recursively when they dissappear. More testing
for B_ENTRY_MOVED. Optimizations are possible when some information is
retrieved twice. I am also planning to add a way for the BPathMonitor user to
filter the automatically watched files/folders in B_WATCH_RECURSIVELY mode.
I grepped the entire Haiku tree for usage of BPathMonitor. Only net_server
and Mail were using it, but both in a way that is not affected by these
changes. Anyways, TextSearch works more reliable now, even for entries in
subfolders.
Feedback very welcome! :-)

our style guide :-)
