gallium: add PIPE_SHADER_CAP_MAX_OUTPUTS and use it in st/mesa
With 5 shader stages and various combinations of enabled and disabled shaders,
the maximum number of outputs in one shader doesn't have to be equal to
the maximum number of inputs in the following shader.
v2: return 32 for softpipe and llvmpipe
gallium: add a texture target to sampler view and a CAP to use it
This allows a sampler view to have a different texture target than the
underlying resource. This will be used to implement the type casting
between 2d arrays and cube maps as specified in ARB_texture_view.

v2: Reuse opcode gaps as suggested by Marek
This limit is fixed in Mesa core and cannot be changed.
It only affects ARB_vertex_program and ARB_fragment_program.
The minimum value for ARB_vertex_program is 1 according to the spec.
The maximum value for ARB_vertex_program is limited to 1 by Mesa core.
The value should be zero for ARB_fragment_program, because it doesn't
support ARL.
Finally, drivers shouldn't mess with these values arbitrarily.

gallium: add texture gather support to gallium (v3)
This adds support to gallium for a TG4 instruction,
and two CAPs. The first CAP is required for GL_ARB_texture_gather.
The second CAP is required to expose GL_ARB_gpu_shader5.
However so far we haven't found any hardware that natively
exposes the textureGatherOffsets feature from GL, so just
lower it for now. If hardware appears for this we can add
another CAP to allow TG4 to take 4 offsets.
v2: add component selection src and a cap to say
hw can do it. (st can use to help control
GL_ARB_gpu_shader5/GLSL 4.00). Add docs.

Some of the hardware support is missing. The NVIDIA-provided driver,
which claims seamless cube map support fails the relevant tests as well.
As this is the last extension before we can have OpenGL 3.2, doing this
allows us to expose geometry shaders without doing the additional
work involved in supporting ARB_geometry_shader4.

nv50: add support for texelFetch'ing MS textures, ARB_texture_multisample
Creates two areas in the AUX constbuf:
- Sample offsets for MS textures
- Per-texture MS settings
When executing a texelFetch with a MS sampler, looks up that texture's
settings and adjusts the parameters given to the texfetch instruction.
With this change, all the ARB_texture_multisample piglits pass, so turn
on PIPE_CAP_TEXTURE_MULTISAMPLE.

First off, nv50_program only has 16 in/out varyings. However reporting
16 makes 'm' become 68 in nv50_fp_linkage_validate with the
varying-packing-simple piglit test. (Subverting the assert makes it
compile but fail.) With this patch, varying-packing-simple passes.
