276d8057aa glx: Fix memory leak in context garbage collection (v2)
I broke this, back in:

	glx: Reimplement context tags

In that, I changed the glx client state to not explicitly track the list
of current contexts for the client (since that was what we were deriving
tags from).  The bug was that I removed the code for same from
glxClientCallback without noticing that it had the side effect of
effectively de-currenting those contexts, so that ContextGone could free
them.  So, if you had a client exit with a context still current, the
context's memory would leak.  Not a huge deal for direct clients, but
viciously bad for indirect, since the swrast context state at the bottom
of Mesa is like 15M.

Fix this by promoting Bool isCurrent to ClientPtr currentClient, so that
we have a back-pointer to chase when walking the list of contexts when
ClientStateGone happens.

v2: Explicitly call __glXFreeContext on the ClientStateGone path.  Our
current context might be one we got from EXT_import_context and whose
creating client has since died.  Without the explicit call, the creating
client's FreeClientResources would not free the context because it's
still current, and the using client's FreeClientResources would not free
the context because it's not an XID it created.  This matches the logic
from a48dadc.

eabb523aa4 glx: Allow float renderType in glXCreateContextAttribsARB
This enables GLX_RGBA_FLOAT_TYPE_ARB and
GLX_RGBA_UNSIGNED_FLOAT_TYPE_EXT as valid renderType parameters to
glXCreateContextAttribsARB.

v2 (idr) : Use C-style comments and fix word wrapping.  Re-write commit
message.

90aa2486e3 glx: Allow attributes and flags from GLX_ARB_create_context_robustness
The assumtion is that if the underlying provider (e.g., glxdri2.c) doesn't
support this extension, it will generate BadMatch for these flags and
attributes.

aef0b4593e glx: Track the reset notification strategy for a context
Also require that the reset notification for a new context and the other
context in the share group match.  There isn't yet any way to specify a
non-default reset notification strategy, but that will come.

41d5120eaf glx: Implement GLX_EXT_create_context_es2_profile
This patch builds on the infrastucture put in place for
GLX_ARB_create_context_profile.  If GLX_CONTEXT_ES2_PROFILE_BIT_EXT is
specified and the requested version is 2.0, create a context with the
__DRI_API_GLES2 API.

This change assumes that any DRI2 driver can handle (possibly by saying "no
seeing an API setting other than __DRI_API_OPENGL or __DRI_API_OPENGL_CORE.
This allows enabling the extension any time GLX_ARB_create_context (and
GLX_ARB_create_context_profile) is enabled.

v2: Clean up some comments.  Note that our behavior for
GLX_CONTEXT_ES2_PROFILE_BIT_EXT w/version != 2.0 matches NVIDIA's.

cef0b808d3 glx: Implement GLX_ARB_create_context_profile
Most of the infrastructure was already in place.  This just adds:

    * Validate values specified with the GLX_CONTEXT_PROFILE_MASK_ARB
      attribute.

    * Select a DRI2 "api" based on the setting of
      GLX_CONTEXT_PROFILE_MASK_ARB.

    * Enable GLX_ARB_create_context_profile extension.

This change assumes that any DRI2 driver can handle (possibly by saying "no")
seeing an API setting other than __DRI_API_OPENGL.  This allows enabling this
extension any time GLX_ARB_create_context is enabled.

Also, the validation code in __glXDisp_CreateContextAttribsARB is structured
in a very verbose manner (using a switch-statement) to ease the addition of
GLX_EXT_create_context_es2_profile.

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
