2a5cbc17fc glx: Add safe_{add,mul,pad} (v3) [CVE-2014-8093 4/6]
These are paranoid about integer overflow, and will return -1 if their
operation would overflow a (signed) integer or if either argument is
negative.

Note that RenderLarge requests are sized with a uint32_t so in principle
this could be sketchy there, but dix limits bigreqs to 128M so you
shouldn't ever notice, and honestly if you're sending more than 2G of
rendering commands you're already doing something very wrong.

v2: Use INT_MAX for consistency with the rest of the server (jcristau)
v3: Reject negative arguments (anholt)

abf1202706 glx: Move the GLX variable caching what GL context is current to dix.
GLX is trying to track whether the context it wants is current, to
avoid the glFlush() (and the rest of the overhead) that occurs on all
MakeCurrent calls.  However, its cache can be incorrect now that
glamor exists.  This is a step toward getting glamor to coordinate
with GLX.

be6680967a glx: convert to direct GL dispatch (v2)
We now expect to be linked against something that provides the GL API,
instead of manually grubbing about in the DRI driver's dispatch table.
Since the GLX we expose calls GL functions that are meant to be looked
up dynamically, also add a way to thunk through to GetProcAddress.

This includes a refresh of the generated sources, which requires a
correspondingly new Mesa.

The GetProcAddress stubs are at the moment merely enough to make this
link against Mesa 9.2, but should really be provided for everything not
in the OpenGL 1.2 ABI.

v2: Explicitly hide the GetProcAddress stubs so we can't conflict with
libGL symbols; fix leading tab/space issues [anholt]

06ac7937fc Restore extern to the declaration of __glXDRISWRastProvider
b86aa74 dropped the 'extern' from the declaration of __glXDRISWRastProvider

This turns out to be important to me, as without it, the final link only gets
the tentative definition of __glXDRISWRastProvider implied by the declaration,
and not the proper one from glxdriswrast.c, presumably because nothing else
references anything in the object that file generates.

8aa6d49d46 glx: Don't request prototypes for GL extension functions
The server does not want GL extension prototypes.  It never links with
anything that could possibly provide implementations of these functions.  It
*is* the provide, and it does not provde these symbols.  All this does is
create hundreds of warnings like:

incude/GL/glext.h:5570:45: warning: redundant redeclaration of 'glMultTransposeMatrixd' [-Wredundant-decls]
include/GL/gl.h:1940:45: note: previous declaration of 'glMultTransposeMatrixd' was here

I believe this was necessary back before the AIGLX days, but that was a long,
long time ago.  The warnings recently showed up with the addition of
-Wredundant-decls to the CWARNFLAGS.

v2: Update the commit message, no code changes.

9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

a48dadc98a glx: Reimplement context tags
This would let you do a constant-time context lookup, but if that's your
performance problem you have two problems.  Just use the context's XID
as the tag value instead.

In order to do this, we have to defer destroying a context until it
actually goes unreferenced, as you're allowed to mention a context tag
after you've (ostensibly) destroyed the context, as long as it's still
your current context.  Thus, change DestroyContext to merely mark the
context as dead if it's a current context, and call down to actual
resource destruction (and XID reclamation) in StopUsingContext.

Also, stop trying to delete context state from DrawableGone.  This was
always broken, as GLX does not say that contexts are destroyed when
their drawables are destroyed.  But with the above change to defer
context destruction, this would trigger a server crash on client exit as
we'd free the context state twice.

619c4d60eb glx: Replace broken GLX visual setup with a fixed "all" mode.
With trying to match depths so that you didn't end up with a depth 24
fbconfig for the 32-bit composite visual, I broke the alpha bits on the depth
24 X visual, which angered other applications.  But in fixing that, the
pickFBconfigs code for "minimal" also could end up breaking GLX visuals if
the same FBconfig was chosen for more than one X visual.
We have no reason to not expose as many visuals as possible, but the old
"all" mode didn't match any existing X visuals to GLX visuals, so normal
GL apps didn't work at all.

Instead, replace it with a simple combination of the two modes: Create GLX
visuals by picking unique FBconfigs with as many features as possible for
each X visual in order.  Then, for all remaining FBconfigs that are
appropriate for display, add a corresponding X and GLX visual.

This gets all applications (even ones that aren't smart enough to do FBconfigs)
get all the options to get the visual configuration they want.  The only
potential downside is that the composite ARGB visual is unique and gets a
nearly full-featured GLX visual (except that the root visual might have taken
the tastiest FBconfig), which means that a dumb compositing manager could
waste resources. Write compositing managers using FBconfigs instead, please.
