I am not sure how to properly handle flat shading regarding
non color parameter to fragment shader. It seems we should
still interpolate non color using linear interpolation and
flat shade only apply to color.

Split hw vs pipe states creation handling as hw states group doesn't
match pipe state group exactly. Right now be dumb about that and
rebuild all hw states on each draw call. More optimization on that
side coming.

Previous patch added literal emission to wrong place, we
want to emit literal before emitting a new alu group.

Add texture mapping support, redbook/texbind works if
you comment out glClear and second checkboard. Need to
fix :
- texture overwritting
- lod & mip/map handling
- unormalized coordinate handling
- texture view with first leve > 0
- and many other things

Fixes SCons build.

Make sure we always fill in the literal after alu instruction.

This add texture support to the assembler, generated code is
wrong (tested against working dump).

We need to make sure dp are all mirror accross the alu unit.

Could serve as an example on how to add more token
support.

Writing a compiler is time consuming and error prone in
order to allow r600g to further progress in the meantime
i wrote a simple tgsi assembler, it does stupid thing but
i would rather keep the code simple than having people
trying to optimize code it does.

some of the ALU instructions are different on r6xx vs r7xx,
separate the alu translation to separate files, and use family
to pick which compile stage to use.

before this change, r600 glxinfo segfaulted in the list code, and I wasn't
debugging another linked list implementation, its 2010 after all.
So add the two missing list macros to the gallium header from X.org list header file (after fixing them), then port all r600 lists to the new header.

- enabled flushing a buffer more than once
- enabled the blitter for r600_clear
- added some more colors to r600_is_format_supported (copied from r600_conv_pipe_format)
- r600_set_framebuffer_state now sets rctx->fb_state
- more states are saved before a blit (had to add some accounting for the viewport and the vertex elements state)
- fixed a few errors with reference counting
