Mesa no longer supports rendering to anything less. GLX 1.2 requires
that the server advertise at least one GLX visual. GLX 1.3 and 1.4 are
more subtle: they require at least one fbconfig capable of window
rendering, and _also_ require that window-capable fbconfigs have a
non-zero value for the GLX_VISUAL_ID. In either case we should refuse
to init GLX if there's not at least one GL-capable visual on at least
one screen.

I've been seeing sporadic (anywhere from once every few days to 3-4
times a day) crashes and freezes in X. The problematic behaviour isn't
always the same, but I chose a particular incident to debug, and found
that X was segfaulting in updateMotionHistory, on line 575 of
dix/getevents.c.
After some further investigation, I found that the bug was being
triggered when a SIGIO was received in DeepCopyPointerClasses, between
the AllocValuatorClass call (line 540) and updating the to->valuator
pointer (line 545). AllocValuatorClass calls realloc() on to->valuator,
so between these lines, it's not guaranteed to point to allocated
memory.
It seems the SIGIO handler is calling updateMotionHistory, which is
reading the memory pointed to by to->valuator and getting a wrong value
for last_motion, which updates buff to point to wildly the wrong place
and thus generates a segfault when a memcpy() is done into buff.
I am attaching a patch which I've been running on that machine for the
past three days, and haven't yet observed any more crashing or freezing
behaviour. The patch simply calls OsBlockSIGIO while
DeepCopyDeviceClasses is in progress, as the state of the X server's
device data structures is not guaranteed to be in a consistent state
during that time.

This requires renaming pnprintf to vpnprintf and changing the size_t to int to

supposed to be called from miXYToWindow which resets spriteTraceGood to 1,
thus DeepestSpriteWindow() is always the root window anyway.

GetGlyphs is supposed to always return the full list of characters
when there is a default character available. However, if an
application opens a 16-bit two dimensional font and then draws with
8-bit requests, the bitmapGetGlyphs function in libXfont versions up
through 1.4.7 will return zero glyphs if there is no 0th row.
While this is a bug in libXfont and should be fixed there, it's easy
to protect glamor from it by simply falling through to the case that
handles GetGlyphs failures for fonts without a default character.

We can only request one fd per device from systemd-logind. If a fd is re-used
by the same device, releasing the fd from one device doesn't mean we can close
it. The systemd code knows when it's really released, so let it close the fd.
Test case: xorg.conf section for an input device with hotplugging enabled.
evdev detects the duplicate and closes the hotplugged device, which closes the
fd. The other instance of evdev thinks the fd is still valid so now you're
playing a double lottery. First, which client(s) will get the evdev fd?
Second, which requests will be picked up by evdev and which ones will be
picked up by the client? You'll never know, but the fun is in finding out.

This patch introduces a new key MatchSeat in xorg.conf (also applies to
any .conf file in xorg.conf.d). It will allow targeting a given
"Device", "Screen", and/or "ServerLayout" section to a particular
seat only (specified by option "-seat" in X server command line),
so that other seats won't be affected.
Without this patch, one needs to write a separate xorg.conf.custom
file and pass it to X server via "-config" option, if one wants that
these settings only apply for the right seat. However, in some cases,
this solution is undesirable or even impossible (e.g. when using GDM,
which doesn't allow X server command line customization).
Example file (/etc/X11/xorg.conf.d/seat1.conf), which would be ignored
by X server unless it was started with "-seat seat1" option:
Section "Device"
Identifier "card0"
Driver "nvidia"
Option "NoLogo" "True"
MatchSeat "seat1"

This breaks compilation on ARM, since out{b,w,l}() are redefined using
the preprocessor and therefore cause the compiler to complain about
non-existent fields being assigned to.
It seems like the compiler.h header that contains these redefinitions
