Use a #define instead of a magic number
The number of buffers is likely to change in the future, so having
this as a define is the right way to go.

DRI2: Force allocation of real-front buffer for non-windows as well
For redirected rendering we end up with pixmaps (which the app thinks are
windows) that are double buffered.

DRI2: Implement protocol for DRI2GetBuffersWithFormat
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.
