This fixes fbo-readpixels piglit test, and adds support for swapping
the formats. Not all formats are correct yet I don't think.

Simplify state handly by avoiding state allocation.
Next step is to allocate once for all context packet
buffer and then avoid rebuilding pm4 packet each time
(through use of combined crc) this would also avoid
number of memcpy.

Make sure LIT fills all slot for instruction (can't do W instruction
without having the Z slot filled with at least a NOP).
ALU instruction can't access more than 4 constant, move constant to
temporary reg if we reach the limit.
Fix ALU block splitting, only split ALU after ALU with last instruction
bit sets.

That is, remove pipe_context::draw_arrays, pipe_context::draw_elements,
pipe_context::draw_arrays_instanced,
pipe_context::draw_elements_instanced,
pipe_context::draw_range_elements.
Some drivers define a generic function that is called by all drawing
functions. To implement draw_vbo for such drivers, either draw_vbo
calls the generic function or the prototype of the generic function is
changed to match draw_vbo.
Other drivers have no such generic function. draw_vbo is implemented by
calling either draw_arrays and draw_elements.
For most drivers, set_index_buffer does not mark the state dirty for
tracking. Instead, the index buffer state is emitted whenever draw_vbo
is called, just like the case with draw_elements. It surely can be
improved.
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

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.

Split instruction into scalar in core compiler this simplify
the way we translate the instruction in latter stage.

Disable rendering to avoid GPU lockup.
Use radeondb to debug shader compiler :
radeondb -c gallium.bof
radeondb -s gallium.json
Will print shader generated, best is to use fp demos to test
the compiler.

- 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
Change the way we translate from c_compiler to the
asic specific representation. Should make things
simpler.

- Wrapped the buffer and texture create/destroy/transfer/... functions
using u_resource, which is then used to implement the resource functions.
- Implemented texture transfers.
I left the buffer and texture transfers separate because one day we'll
need a special codepath for textures.
- Added index_bias to the draw_*elements functions.
- Removed nonexistent *REP and *FOR instructions.
- Some pipe formats have changed channel ordering, so I've removed/fixed
nonexistent ones.
- Added stubs for create/set/destroy sampler views.
- Added a naive implementation of vertex elements state (new CSO).
- Reworked {texture,buffer}_{from,to}_handle.
- Reorganized winsys files, removed dri,egl,python directories.
- Added a new build target dri-r600.
