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.
