[Mesa-dev] [RFC] i965: Attempt to merge some surface state setup logic

[Topi Pohjolainen]

First five patches refactor common decision making found in depth,
texture and renderbuffer surface setup logic.

In principle, there is opportunity to share code between texture and
renderbuffer setup logic (Kenneth has experimented with this earlier [1]).
On the other hand there is also a lot of overlap between gen7 and
gen8 renderbuffer paths (same applies for paths dealing with texture
surfaces). I tried this in the last patch, and I like the way the code
looks afterwards.

Anyway, I don't have strong preference which way to go and thought
better to share the work before running regression tests on all
SNB, IVB, HSW and BDW involved.

This is based on Jordan's layered rendering and can be found in:
