RADEONDGAInit() even if EXA is enabled; the problematic DGA
acceleration hooks are already disabled in that case.
This fixes DGA issues such as DGA mouse (typically used by games in
fullscreen mode) not working.
Fix suggested by Eric Anholt.
system to build the README file at make dist time
- in util/macros/xorg-macros.m4, add a new XORG_CHECK_LINUXDOC macro that
will check if the required tools and files exist, and if so set a
conditional.
- util/modular/symlink.sh
- Link all the <driver>.sgml to xf86-video-<driver>/README.sgml
- Add all the README.<driver> to the list of excluded files
- xc/programs/Xserver/hw/xfree86/doc/sgml/SiS.sgml: Various changes to make

the function (the code above will cause pixmap cache to be freed and
copied around, and these functions must be called after that otherwise
pixmap damage will occur). May be related to #4440, #4456 (unclear if
these setups involve 3d apps)
hook so we can upload a subset of a pixmap, and convert the current
drivers to respect that. Use this support to directly UploadToScreen in
exaGlyphs, providing a 47.4% +/-2.4% decrease in wall time for ls -lR
programs/Xserver in an antialiased gnome-terminal on an M6 (n=3, caches
hot). I would have bumped major version, only I can't tell what the
EXA_VERSION_* is supposed to be doing as opposed to the module version.

- Disable the shortcut for switching from 3d to 3d in radeon_exa.c. It
appears that we do need the cache flush here, thought it's not clear
why. Disable the 2d to 2d shortcut while here, since I'm unsure of what
we're doing. Exposed by the following bit:
- Bug #4485: Add a new routine, exaGlyphs, to handle font drawing. Glyphs
were being accumulated in from non-migratable scratch pixmaps, causing
the destination pixmap to move towards screen but the migration
necessary for source never to happen, leading to abysmal performance.
Instead, copy the scratch glyph data into a real pixmap first, then
composite from that into the destination, allowing for migration. time
ls -lR from programs/Xserver showed 26.9% (+/- 6.3%) decrease in wall
time (n=3).
- Create exaDrawableUse* wrapping exaPixmapUse*, but which are aware of
windows needing backing store. Makes migration code prettier, and
ensures that composited windows will be migrated as normal when we turn
off cw for EXA. (issue brought up by keithp)
