is there a reason to export this function? Why not having it static?
Meta (mesa/src/main/drivers/common/) uses _mesa_BufferData. It would
be simpler to use this function _mesa_buffer_data. After most of DSA
is done, I get to start making Meta use the backend functions rather
than api entry points. This will hopefully save us from storing
internal driver objects in hash tables and getting the context everywhere.
