i965: Split surface format code into a new file (brw_surface_formats.c).

brw_wm_surface_state.c has gotten rather large and unwieldy.  At this
point, it consists of two separate portions:

1. Surface format code

   This includes the giant table of surface formats and what features
   they support on each generation, as well as the code to translate
   between Mesa formats and hardware formats.

   This is used across all generations.

2. Binding table (SURFACE_STATE) related code.

   This is the code to generate SURFACE_STATE entries for renderbuffers,
   textures, transform feedback buffers, constant buffers, and so on, as
   well as the code to assemble them into binding tables.

   This is only used on Gen4-6; gen7_surface_state.c has Gen7+ code.

Since the two are logically separate, and one is reused on every
generation while the other is not, it makes a lot of sense to split
them out.  It should also make finding code easier.

No code is changed by this patch.  I simply copied the file then deleted
portions of both.

Also, the "minimum resolvable depth difference" used isn't really right as it
should be calculated according to the z values of the current primitive
and not be a constant (of course, this only makes a difference for float

This patch fixes segfaults observed when enabling the post processing

llvmpipe: add support for nested / overlapping queries

OpenGL doesn't support this but d3d10 does.
It is a bit of a pain as it is necessary to keep track of queries
still active at the end of a scene, which is also why I cheat a bit
and limit the amount of simultaneously active queries to (arbitrary)
16 (simplifies things because don't have to deal with a real list
that way). I can't think of a reason why you'd really want large
numbers of overlapping/nested queries so it is hopefully fine.
(This only affects queries which need to be binned.)

v2: don't copy remainder of array when deleting an entry simply replace
the deleted entry with the last one (order doesn't matter).
