dri2: Deduplicate attachments in do_get_buffer ...
It was always the intention of the DRI2 protocol that there's at most
one instance of each attachment, and that's how it was implemented in
Mesa.
Since that wasn't enforced though, there might be other clients in the
wild which (e.g. accidentally) request the same attachment multiple
times. So starting to a raise a protocol error in this case now risks
breaking such clients.
Instead, just deduplicate the attachments using a bit-set.
This has a couple of desirable side effects:
* destroy_buffer cannot be called multiple times for the same
DRI2BufferPtr.
* The client cannot cause the server to allocate a buffers array with
more entries than there are attachments (currently 11).
changes by mtx: fix FTBS by dropping now unused have_fake_front variable.
