[Mesa-dev] i965: Yet another revision of tex surface setup refactoring

[Topi Pohjolainen]

Here is a rebase of refactoring originally sent in early May. This
is now based on Curro's work and applies on top of the current
master. I chose to re-order my patches in order to keep them as
tiny as possible. Especially the dispatch for the texture buffer
surfaces is split in two parts - one patch introducing it in the
common dispatcher and second dropping the redundant calls left in
gen7 and gen8 specific logic while moving to use Curro's
emit_texture_surface_state() instead of update_texture_surface().

End result is a common dispatcher making the decisions for
values in common code while leaving the hardware specific parts to
deal with batch formatting only. The series also moves gen < 7
logic to use the same hooks as the newer allowing us to drop the
other hook (update_texture_surface()) alltogether.

This is mostly motivated by my work on using blorp-style
lightweight launch mechanism for meta blits and clears.
