Robert Bragg e98ee6665b cogl-buffer: Track the last used bind target in CoglBuffer
This makes CoglBuffer track the last used bind target as a private
property. This is later used when binding a buffer to map instead of
always using the PIXEL_UNPACK target.

This also adds some additional sanity checks that code doesn't try to
nest binds to the same target or bind a buffer to multiple targets at
the same time.
