accelerants: Add default case for xy_command initialization.

Silences a GCC 11 warning.

Style cleanups only, no functional change.
* Make the pointer style consistent accross all components, which should make it
easier when working all over the place.
* 80 char limits.

Work in progress (might not work for you yet):
* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.

* Made QueueCommands::Write() and MakeSpace() public.
* Implemented MakeSpace() (not yet tested).
* Changed intel_wait_engine_idle() to spin() between reads and to timeout
after 1 second of waiting (could probably be done way earlier).

* Implemented B_FILL_SPAN - I am not sure if it's used at all, though, so
I am also not sure if it's working correctly.
* Minor cleanup.

Say hello to B_FILL_RECTANGLE and B_INVERT_RECTANGLE - only B_FILL_SPAN is missing
from the acceleration hooks in BeOS.

* Turns out the virtual messes with the data in struct command, so we can't
use it (which isn't really that bad).
* B_SCREEN_TO_SCREEN_BLIT is now working as intended, so we can finally move
windows and scroll at decent speed :-)
* Implemented a simple version of B_WAIT_ENGINE_IDLE for now.

Started implementing screen-to-screen blits, not yet tested.

Prepared support for acceleration: there is now a QueueCommands class that should
be used to feed the ring buffers with new commands. It takes care about proper
alignment (this shouldn't be necessary in the final version, anymore, though), and
locking.
