This creates a cleaner winsys and drop the simple screen stuff.
It makes r300g use pb_bufmgr structs.
It also tries to avoid overheads from mapping too often.
v5: clean warnings
v6: break out of cache check on first buffer - since most likely
the first busy one implies all after it are busy.
v7: cleanup a bit
v8-merged: drop cman for now to just get all the interface changes in first.

r300g: decouple vertex stream setup (PSC) and VS output mapping (VAP_OUT)
Formerly known as vertex_format_state. These two are completely
unrelated when using HWTCL and decoupling them makes the design
less SWTCL-centric.
When bypass_vs_clip_and_viewport gets removed, the PSC setup will
no longer be a derived state.
This change shouldn't make unbreaking SWTCL harder.
Revert "r300g: rebuild winsys/pipe buffer handling and add buffer map"
This reverts commit fff5be8e7b.
Probably went too soon with this, dileX reported OA not working for him
it works here fine, but the optimisations I wanted aren't working properly
yet so I'll fix that now.

r300g: rebuild winsys/pipe buffer handling and add buffer map
This creates a cleaner winsys and drop the simple screen stuff.
It makes r300g use pb_bufmgr structs and adds usage of the cached
bufmgr for vertex/index buffers.
It also avoids mapping too often.
I'm not 100% sure this is perfect but it won't find its own bugs.

r300g: set the correct tiling flags for renderbuffers
MACRO_SWITCH is applied to samplers but not renderbuffers. This commit
fixes incorrect rendering to large and small mipmaps where the large ones
are macrotiled and the small ones are not and both are emitted
in the same CS.
Note that this is still disabled by default (rework of texture transfers
is next).
gallium: make max_anisotropy a unsigned bitfield member
saves us a dword in sampler state, hw can't do non-integer aniso degree anyway.
To allow aniso 1x (which seems of dubious value but some hardware (radeons)
have such a mode, and even d3d allows specifiying it) redefine anisotropic
filtering as disabled only if max_anistropy is 0.
