The i915 GPU can't do A8 dst, so we abuse GREEN8 buffers for that
purpose. However, things get hairy as we start to do blending,
because then GL_DST_*_ALPHA should be replaced with GL_DST_*_COLOR.
This is what we do here.
Fixes piglt fbo-alpha.

Create the video buffers in the format the driver preffers.
This temporary creates problems with decoder less VDPAU video playback.

Add a second extened constructor that takes plane
textures for the video buffer. Also provide a
function for texture templates.

This requires GLSL 1.30 enabled, which requires integer types enabled,
so don't bother doing an INT to FLT conversion on it.
We should probably remove the instance id flt->int conversion when
turning on native integers.
this passes the three piglit tests with GLSL 1.30 forced on.

This commit rewrites a lot of the state_fb code to support
rendering to targets not aligned to 64 byte.
This allows us to drop the render temporaries as unaligned
targets are the only use-case where they are really needed. The
temporaries code was used for a lot of things more, but apparently
those also work without temps.
There is one regression in piglit fbo-clear-formats, but this will
be fixed with the use of real hardware clears and doesn't matter in
practice as no real application tries to scissor clear a 2x2 pixel
render target.

There are 3 changes:
1) stride is specified for each buffer, not just one, so that drivers don't
have to derive it from the outputs
2) new per-output property dst_offset, which specifies the offset
into the buffer in dwords where the output should be stored,
so that drivers don't have to compute the offsets manually;
this will also be useful for gl_SkipComponents
from ARB_transform_feedback3
3) register_mask is removed, instead, there is start_component
and num_components; register_mask with non-consecutive 1s
doesn't make much sense (some hardware cannot do packing of components)
Christoph Bumiller: fixed nvc0.
v2: resolve merge conflicts in Draw and clean it up
Virtual address space put the userspace in charge of their GPU
address space. It's up to userspace to bind bo into the virtual
address space. Command stream can them be executed using the
IB_VM chunck.
This patch add support for this configuration. It doesn't remove
the 64K ib size limit thought this limit can be extanded up to
1M for IB_VM chunk.
v2: fix rendering
v3: fix rendering when using index buffer
v4: make vm conditional on kernel support add basic va management
v5: catch the case when we already have va for a bo
v6: agd5f: update on top of ioctl changes
v7: agd5f: further ioctl updates

Flat SHADE_MODEL still overrides any non-flat interpolation
qualifier, but pulling that state out of the rasterizer cso
isn't really worth the effort, is it ?
NOTE: This is a candidate for the 8.0 branch.
We include both imports.h and u_math.h in the state tracker. This
leads to multiple, conflicting definitions of ffs() with MSVC.
Use FFS_DEFINED to skip the ffs() in u_math.h.

svga_sampler_view contains a pointer to a pipe_resource (base class of
svga_texture) and svga_texture contains a pointer to an svga_sampler_view.
This circular dependency prevented the objects from ever being freed when
they pointed to each other. Make the svga_sampler_view::texture pointer
a "weak reference" (no reference counting) to break the dependency.
This is safe to do because the pipe_resource/texture always has a longer
lifespan than the sampler view so when svga_sampler_view stops referencing
the texture, the texture's refcount never hits zero.
Fixes a memory leak seen with google earth and other apps.

Prevent any state from carrying over to a new translation in cases
where we assume that data is still zero from initial calloc (these
would require us to do individual zeroing before translation which
would be more code).
