As of v4 of this extension, any GLES version number may be requested (to
enable GLES3 and later). To comply with this, simply remove the API
version checks and leave it to the DRI driver to validate. This happens
to also enable using GLES1 in direct contexts, so if that's the dire
situation you find yourself in, your client driver at least stands a
chance of working.
v4 also specifies that both extension strings should be advertised for
compatibility with clients written against v1 of the extension spec, so
add the es_profile bit to the extension list and enable it whenever we
would enable es2_profile.

This extension allows clients to opt out of the implicit glFlush on
context release, which is quite nice for performance for clients using
multiple contexts. The server doesn't really need to be aware of the
client's decision, at least for direct contexts, but it does need to not
reject the context attribute out of hand.
This patch won't do anything unless built against a Mesa that defines
the __DRI2_FLUSH_CONTROL extension (and a new enough glxext.h, but
that's been there since 10.3 at least).

With the previous patches applied, we now have crash due to use-after-free when
a client exits without deleting all it's GL contexts
On client exit, CloseDownClient first calls glxClientCallback() with
ClientStateGone, which calls __glXFreeContext() directly.
Subsequently CloseDownClient() frees all the clients resources, which leads to
ContextGone() being called for a context resource where the context has already
been freed.
Fix this by modifiying glxClientCallback() to free the context resource.
Also make __glXFreeContext() static, as calling it directly leads to this
problem, instead the context resource should be released.
With the previous patches applied, this can be demonstrated with e.g. glxinfo,
which doesn't delete it's context before exit.

Well, that was lame. The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth. So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.
So until the DRI drivers are fixed we should just continue to lie about

Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and
three releases ago. The main reason to have wanted DRI1 AIGLX was to
get a GLX compositor working, but DRI1's (lack of) memory management API
meant that the cost of a GLX compositor was breaking direct GLX apps,
which isn't a great tradeoff.
Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose
some functionality here, since it and only it has support for
NV_texture_rectangle. Since that's required for every extant GLX
compositor I know of, I conclude that anybody with a savage, say, would
probably not notice AIGLX going away, since they wouldn't be running a
GLX compositor in the first place.
In the future we'd like to use GL in the server in a more natural way,
as just another EGL client, including in the GLX implementation itself.
Since there's no EGL implemented for DRI1 drivers, this would already
doom AIGLX on DRI1 (short of entirely forking the GLX implementation,
which I'm not enthusiastic about).

Losing the drawable does not change our notion of current client. Since
the GL under us doesn't understand having a current context without
current drawables (sigh), we do still need to loseCurrent so that we
re-bind the context on the next request.

I broke this, back in:
commit a48dadc98a
Author: Adam Jackson <ajax@redhat.com>
Date: Mon Mar 21 11:59:29 2011 -0400
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.

In __glXScreenInit() we generate the set of GLX visuals in two steps:
first we match each pre-existing X visual with a corresponding
FBConfig, then we generate a new X visual to correspond to all the
remaining FBConfigs.
The first step is used for the two default 24-bit visuals (true color
and direct color) and for the 32-bit visual. If windowsystem
multisampling is enabled in Mesa, we need to ensure that none of these
three visuals gets matched to a multisampled config.
Fixes a bug with windowsystem multisampling in gnome-shell. If the X
server happens to match up a multisampled FBConfig to the 32-bit
visual, gnome-shell will try to use it to read pixels from
alpha-blended windows (such as gnome-terminal), resulting in no window
appearing on screen.

This adds the initial prime support for dri2 offload. The main thing is
when we get a connection from a prime client, we stored the information
and mark all drawables from that client as prime. We then create all
buffers for that drawable on the prime device dri2screen.
Then DRI2UpdatePrime is provided which drivers can call to get a shared
pixmap which they can use as the front buffer. The driver is then
responsible for doing the back->front copy to the shared buffer.
prime requires a compositing manager be run, but it handles the case where
a window get un-redirected by allocating a new pixmap and pointing the crtc
at it while the client is in that state.
Currently prime can't handle pageflipping, so always does straight copy swap,
