The old DRI2 buffer allocation API wasn't great, but there's no reason to
make the server stop working with those drivers. This patch has the
X server adapting to the API provided by the driver, using the new API where
available and falling back to the old API as necessary. A warning will be
placed in the log file when the old API is in use.

For redirected rendering we end up with pixmaps (which the app thinks are
windows) that are double buffered.

This change implements the protocol for DRI2GetBuffersWithFormat, but
the bulk of the differences are the changes to the extension / driver
interface to make this function work. The old CreateBuffers and
DeleteBuffers routines are replaced with CreateBuffer and DeleteBuffer
(both singular).
This allows drivers to allocate buffers for a drawable one at a time.
As a result, 3D drivers can now allocate the (fake) front-buffer for a
window only when it is needed. Since 3D drivers only ask for the
front-buffer on demand, the real front-buffer is always created. This
allows CopyRegion impelemenations of SwapBuffers to continue working.
As with previous version of this code, if the client asks for the
front-buffer for a window, we instead give it the fake front-buffer.

If a front-buffer is requested for a window, add the fake front-buffer
to the list of requested buffers.

This prevents building an older server with a new dri2proto.h from
resulting in a DRI2 extension module that lies about the version it
supports.

This copies over the files generated from mesa/src/mesa/glapi. There's
a corresponding mesa commit that makes it easy to generate the glapi files
straight into the xserver tree when the XML definitions change.
The only few files that are copied from mesa but aren't generated are
glapi.[ch] and glthread.[ch]. Everything in there is technically DRI
driver API and the whole setup is still a bit fragile, but it's not a new
problem.
The --with-mesa-source configure option is still around since other
parts of the server (XGL and DMX - grep for MESA_SOURCE) need that,
but for common case of building with GLX and AIGLX support, that
option is no longer needed.
Get rid of glcontextmodes.[ch] from build, rename __GlcontextModes to
__GLXcontext. Drop all #includes of glcontextmodes.h and glcore.h.
Drop the DRI context modes extension.
Add protocol code to DRI2 module and load DRI2 extension by default.
