gallium/svga: Upload only parts of user-buffers that we actually use
Stream user buffer contents rather than trying to maintain persistent
host / hardware copies.
Resulting negative array offsets are not allowed by the hardware,
(well, at least not according to header files), so adjust index bias
to make all array offsets positive.
