include/protocol-versions.h specifies each extension version as supported by
the server and sent back on the wire to the client.
This fixes up several issues with the server potentially reporting a higher
version of the protocol if recompiled against a newer version of the
protocol.

Referencing a screen through a drawable only requires GetAttr access.
Treat dri2 drawables as child windows (Add/Remove access).
Treat getting buffers as intent to read/write the drawable.

These old interfaces are no longer supported by the server, removing them
requires bumping the video driver ABI. Note that this is not guaranteed to
be the last change in ABI version 6.

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.

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.

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.

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

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.
