Formerly the code claimed it could only handle up to 256 visuals, which
was true. Also true, but not explicitly stated, was that it could only
handle visuals with VID < 256. If you have enough screens, and subsystems
that add lots of visuals, you can easily run off the end. (Made worse
because we allocate visual IDs from the same pool as XIDs.) If your app
then chooses a visual > 256, then the Xinerama code would throw BadMatch
on CreateColormap and your app wouldn't start.
With this change, PanoramiXVisualTable is gone. Other subsystems that
were using it as a translation table between each screen's visuals now
use a PanoramiXTranslateVisual() helper.
RISC chips that trap on unaligned loads and stores need to
define __GLX_ALIGN64. This used to get added to the cflags
in the old *.cf files but it no longer does in the modular
X server.
Also, Alpha needs to pass -mieee to the compiler as well.
This is a simple backport of a patch that debian, and probably other
distributions, have been applying forever. To the best of my
knowledge the patch was written by Jurij Smakov. See Debian bug
number #388125.
I just checked and this has been rotting for more than a year in
freedesktop bugzilla as #8392.

Get rid of almost all uses of these definitions. They're still defined for
delinquent out-of-tree drivers, and also for the Mesa build. As well as
for miinitext.c. But largely gone.
