updates during the vertical refresh, but it causes flickering again since
there is no guarantee that screen regions will stay clean from the time that
they were scheduled with the UpdateQueue until the UpdateQueue thread
transfers them. Therefor it is still disabled.
* Refactored a bit the distinction between Invalidate() and CopyToFront().
Invalidate() used to be virtual, but now CopyToFront() is. This was mainly
needed for the app_server test environment, because the host window needs
to call Invalidate() when the front buffer bitmap is clean. When the
UpdateQueue is used, this needs to be CopyToFront(). Now the separation is
cleaner in combination with the UpdateQueue.
* Fixed a problem in HWInterface::CopyToFront(): When separating the region
outside the cursor and the region with the cursor during a transfer, it
needs to hold the fFloatingOverlay lock to make sure the cursor is not
moved in the meantime. This fixes graphics glitches with remnants of the
cursor staying on screen. These could very rarely be observed, but much more
often with the accelerated double-buffer mode.
* Enabled the accelerated double buffered mode, since it works now very well.
I was able to test it with the nVidea driver on an nVideo 7300. It works by
allocating a frame buffer twice the height of the configured screen mode.
Then all drawing goes into the offscreen portion, including accelerated
driver functions. AccelerantHWInterface::_CopyToFront() then uses acceleration
to blit the clean regions in the offscreen portion of the frame buffer into
the visible part. Please tell me if there are problems, for example when
if there is too few video memory, or if a driver does not handle it correctly.
To disable it, see src/servers/app/drawing/AccelerantHWInterface.cpp line 511.

when the HWInterface was using acceleration and at the same time double
buffering.
* _CopyToFront() should always be used, since it calls a protected virtual that
derived classes of HWInterface depend on. This fixes some graphics glitches
in certain situations.

* vm_clone_area() does now set the B_SHARED_AREA flag on both the source
and the cloned area. This is necessary, since it would no longer be
guaranteed that areas are backed by leaf caches only (after
fork()ing), which doesn't work with our cache merging strategy.
Fixes#2605.

initializes the engine lock and a few other things, fixing the deadlock in
ticket #2893. This also seems to result in somewhat improved graphics
performance, at least on my X800.

This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference
counted now.
This optimization reduces the kernel time of the Haiku build on my
machine with SMP disabled a few percent, but interestingly the total
time decreases only marginally. Haven't tested with SMP yet, but for
full impact CPU affinity would be needed.

manually types in or pastes a destination path and then immediately clicks
Expand, the actual destination path used is never updated. Thanks to Daniel
Teixeira for reporting.

it will differ with the keymap, but will usually be the key below the escape
key.

this doesn't work yet.

scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine
(e.g. a non-SMP scheduler on a non-SMP machine).

ctrl-alt-del pressed for 4 seconds, the system will reboot.

the keyboard as well (in BeOS, the reboot is triggered in the device, so it
will also work if the input_server hangs).

* Added a layout friendly constructor - it's not so nice to use, though, since
the original one already doesn't get a BRect (we just don't need the
resizing mode, and have to set the B_SUPPORTS_LAYOUT flag).
* Refactored size/frame computation a bit.
* Cleanup.
