Swrast was missing a free for the culmination of driConcatConfigs.
Use free(), not _mesa_free() since we shouldn't be calling any Mesa
functions from the GLX code. driConcatConfigs() should probably use
regular malloc/free to be consistant but the Mesa functions just wrap
the libc functions anyway.
We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.

(cherry picked from commit 279143c6e8)
Two parts to this:
One we don't keep pointers to possibly freed memory anymore once we unbind the
drawables from the context. Brian I need to figure out what the comment
you made there, can we get a glean/piglit test so we can fix it properly?
If the new gc is the same as the oldGC, we call the unbind even though
we just bound it in that function. doh.

Assume that the front-buffer exists even if the server didn't tell the
client that it exists.

1) If MakeContextCurrent is called with (NULL, None, None), Don't
send the request to the X server if the current context is direct.
2) Return BadMatch in some error cases according to the glx spec.
3) If MakeContextCurrent is called for a context which is current in
another thread, return BadAccess according to the glx spec.

This scheme breaks when the display connection doesn't receive ConfigureNotify
events. This caused reporoducible problems (cropped / misplaced output) when
starting a 3D application in a guest operating system in VMware Workstation.
This reverts commit dd1c68f151.

This requires upgrading the interface so that the argument to
glXBindTexImageEXT isn't just dropped on the floor. Note that this only
fixes the accelerated path on Intel, as Mesa's texture format support is
missing x8r8g8b8 support (right now, GL_RGB textures get uploaded as a8r8gb8,
but in this case we're not doing the upload so we can't really work around it
that way).
Fixes bugs with compositors trying to use shaders that use alpha channels, on
windows without a valid alpha channel. Bug #19910 and likely others as well.

This rewrites the sparc GLAPI code so that it's PIC friendly and works
with all of the TLS/PTHREADS/64-bit/32-bit combinations properly.
As a result we can turn SPARC asm back on. Currently it's only
enabled on Linux, as that's the only place where I can test this
stuff out.
For the moment the cliptest SPARC asm routines are disabled as they
are non-working. The problem is that they use register %g7 as a
temporary which is where the threading libraries store the thread
pointer on SPARC. I will fix that code up in a future change as it's
a pretty important routine to optimize.
Like x86 we do the runtime patch as a pthread once-invoked initializer
in init_glapi_relocs().
Unlike x86, however, our GLAPI stubs on SPARC are just two instruction
sequences that branch to a trampoline and put the GLAPI offset into a
register. The trampoline is what we run-time patch. The stubs thus
all look like:
glFoo:
ba __glapi_sparc_foo_stub
sethi GLAPI_OFFSET(glFOO) * PTR_SIZE, %g3
This actually makes generate_entrypoint() a lot simpler on SPARC. For
this case in generate_entrypoint() we generate stubs using a 'call'
instead of the 'ba' above to make sure it can reach.
In order to get a proper tail call going here, in the unpatched case,
we do several tricks. To get the current PC, for example, we save the
return address register into a temporary, do a call, save the return
address register written by the call to another temporary, then
restore the original return address register value. This is to
avoid having to allocate a stack frame.
This is necessary for PIC address formation.
This new GLAPI scheme lets us get rid of the ugly SPARC GLAPI hacks in
__glXInitialize() and one_time_init().

We only wanted to request when asked for the same set of buffers when a resize
has happened. We can just watch the protocol stream for a ConfigureNotify
and flag to do it then.
This is about a 5% win from doing two glViewport()s per frame in openarena.
