mesa: call DrawBufferAllocate driver hook in update_framebuffer for
windows-system FB

When draw buffers are changed on a bound framebuffer, DrawBufferAllocate()
hook should be called. However, it is missing in update_framebuffer with
window-system framebuffer, in which FB's draw buffer state should match
context state, potentially resulting in a change.

Note: This is needed because gallium delays creating the front buffer,
  i965 works fine without this change.

V2 (Timothy Arceri):
 - Rebased on merged/simplified DrawBuffer driver function
 - Move DrawBuffer call outside fb->ColorDrawBuffer[0] !=
   ctx->Color.DrawBuffer[0] check to make piglit pass.

v3 (Timothy Arceri):
 - Call new DrawBuffaerAllocate() driver function.

Created attachment 139032
  --> https://bugs.freedesktop.org/attachment.cgi?id=139032=edit
WIP fix

I've attached and updated patch which is rebased on the merging of
DrawBuffer/DrawBuffers.

The outstanding issue is that this can cause some of the classic drivers (i915,
radeon, r200) to get stuck in an infinite loop. The problem is these drivers
call _mesa_update_framebuffer() from within the driver when Driver.DrawBuffer()
is called.
