With modern monitors and increased XV and EXA memory requirements, these small
limits were resulting in DRI and other initialization failures because we
wouldn't allow them enough memory. Instead, allow each piece of the system
(DRI, EXA, XAA, etc) to request as much memory as it wants, and choose the
actual videoRam to be used for laying out the memory afterwards.
With this change, in the absence of a VideoRam option, 32MB will be allocated
for textures.
With this, we no longer allocate XV through the XF86 linear allocator in the
EXA case. We also no longer allocate extra space for the XF86 2D allocator
that we don't use in EXA mode, or space for the EXA allocator in XAA mode.
The EXA offscreen allocator now gets enough space for several screenfuls of
pixmaps plus one 1920x1088 movie.
A large duplicated section of code for allocating each framebuffer in the old
dual-screen mode was also factored out.
Some code are duplicated with the new libdrm.
Once this code has been released with xserver,
it can be removed.
See the man page for new options and backwards
3D driver compatibility.
This reverts most of the mergedfb code. This will instead be done in device-
independent RandR code.

patch is based off of diffing from the branchpoint to the supplied code, but
with many chunks containing reversions of commits removed. Won't work yet.
Add Intel 945GM support
Add RandR rotation support (full 3D acceleration, HWcursor & Xvideo rotated too)
Remove shadow framebuffer rotation code
Add a new LinearAlloc option to allow more offscreen memory to be allocated
for XVideo applications. This allows HDTV movies to be played via Xvideo.

RestoreBIOSMemSize() to be exactly opposite to the Save procedure in EnterVT()
(Matthias Hopf, Alan Hourihane).
Fixed server crash on reset when a structure allocated in PreInit() was freed on
CloseScreen().
Fixed ring buffer lock ups that happened because the structure that contained
ringbuffer data was not zeroed after allocation.
Fixed numerous warnings due to signed unsigned comparisons.
are available (Egbert Eich).
Fixed lockups during mode switch. Problem was introduced when attempting to copy
the behavior during LeaveVT()/EnterVT() but but forgetting to call
I810DRILeave() before I810DRIEnter(). The entire DRILeave()/Enter() scenario has
been commented out as it didn't seem to be necessary (Egbert Eich).
Fix TweakMemorySize() (tested with i855/i865) (Egbert Eich).
