Jesse Barnes b180e43977 DRI2: fix swapbuffers handling of SBC and target MSC
Returns expected SBC after completion of swap to caller, as required by
OML_sync_control spec, instead of the last_swap_target value.

Passes target_msc, divisor, remainder, correctly for
glXSwapBuffersMscOML() call, while retaining old behaviour for simple
glXSwapBuffers() call.

An OML swap can have a 0 target_msc, which just means it needs to
satisfy the divisor/remainder equation.  Pass this down to the driver as
needed so we can support it.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
