* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.
All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

node monitoring easier. Also, FileIterator will be split to make the code
cleaner with regards to folder or selection mode.

io() hook directly (it might not even have one).
* Fixed incorrect check in synchronous_io() which would cause requests
with more than one vec to finish early. Fixes bug #2558.

* {read,write}_pages() use vfs_{read,write}_pages() now, instead of
invoking the FS {read,write}_pages() hooks.

printed.

* Moved reservation of memory for the "locked" cases upfront.
Particularly if the would-be area is a kernel area, we don't want the
address space to be write locked while doing that, since that would
block the low memory handler.
* For full lock areas the pages are reserved upfront, too. The reasoning
is similar. Reserve the pages needed by the translation map backend for
mapping the area pages there too.
* Moved the cache locking/unlocking out of the individual cases. All
want to have the cache locked the whole time, now.

given size.

* Renamed it to TextSearch
* Cleaned up the code to match our coding style (already was almost compliant
and the code is very clean and well designed, a pleasure to work with!)
* Fixed memory leaks and potential memory leaks in error codepaths
* Checked the success of most allocations (GrepWindow is missing) and
implemented error code paths
* Simplified the code in a few places
* Fixed bugs in code that iterated over the selected list items and assumed
it found a top level item already while it may not have

before file_cache_write() or nothing had to be written.
* Fixed race condition. While neither transaction nor read lock are
held, the file size can change.
* Add the inode to the transaction whenever possible, i.e. on error
before file_cache_write() and after it as well. This should prevent
readers from seeing inconsistent blocks when the transaction has to be
rolled back.

empty thread structure. This causes the thread::team pointer to be NULL
during the early boot process, but our kernel debugger didn't like that.

when DUMP_FEATURE_STRING is defined to 1.

gTeamSpinlock.
* Renamed the static global variables in smp.c to match our style guide.
* Minor other cleanup.
* Removed superfluous white space.

- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

- iospace should now be initialized correctly, at least the kernel goes much further.

* sCopied wasn't needed anymore due to the sManagedEnviron variable.
* Minor cleanup, added a description to copy_environ_to_heap_if_needed().

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26719 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Improve code in FileUtils to copy attributes in chunks and improve
error checking. Should also copy 0 size attributes now, since those are valid.
* Craft SoundConsumer towards more style guide compliance.
* Use new (std::nothrow) and check result.

running - this fixes several cases where someone could see outdated data
when a transaction had to be reverted (the time between unlocking the inode
and actually reverting the blocks). For that, Inodes can now be put into a
singly linked list.
* Added a TODO in Inode::WriteAt() which explains why it cannot use the above
method: seems that our VFS/VM locking model isn't really that good.
* Fixed a possible deadlock in Attribute::_Truncate() where the inode write
lock was held before starting the transaction.
* Added an InodeReadLocker convenience class, that should be used instead
of ReadLocker - Inode::Lock() only still exists because of the needs of
bfs_io().
* Moved the bfs_io() callback hooks out of the exported module API region,
and removed their bfs_ prefix.
* Added a Volume::IsInitializing() method that should be used rather than
checking if Volume::ID() is >= 0.
* Removed the MultiInodeLocker again, as it's pretty much superfluous now.
* Moved openModeToAccess() to the Utility.h header.
* Minor cleanup.

inode - unlike get_vnode() the busy flag won't prevent you from getting that
reference.
* Changed put_vnode() to return an error in case the vnode couldn't be found.

in steal_pages() which uses the number of pages in the inactive queue as
return criterion. It would thus return, if only marker pages were in the
queue and no page could be stolen. This led to a busy loop in
vm_page_allocate_page(). The whole system would become unusable when the
thread in question was the heap grower, since it would starve everyone
else due to its high priority.
