If the guest is creating texture and the memory
comes from buffer object by creating GL_TEXTURE_BUFFER,
then host creates GL_TEXTURE_BUFFER too.
No texture parameters can be set for GL_TEXTURE_BUFFER.
If there is mismatch between the guest texture format and
the host texture format, for example GL_ALPHA8(guest) and
GL_R8(host), then we can't apply swizzling for such textures.
In such case, add manually swizzling in GLSL shader generation
step.
The logic of this patch:
1. Add additional fields in shader key struct
2. During draw_vbo call check if "manual swizzling" is needed
3. If yes, the add fields in key struct and generate shader again
4. During generation of for example texelFetch instruction
in GLSL put additional instruction for swizzling

Telegram (Android App) shows high cpu usage under

via alpha_src_factor, BLEND_SOFTLIGHT (0x9) would be
treated as PIPE_BLENDFACTOR_SRC1_COLOR (0x9). The
dual_src didn't match dual_src_linked and virgl keeps
linking the same program.

Tipically mesa handles CLAMP_READ_COLOR in gallium frontend, and the
default value for CLAMP_READ_COLOR as defined by the GL spec is
GL_FIXED_ONLY.
As CLAMP_READ_COLOR is really only used for reading pixel color values
from a buffer, there's no problem always returning unclamped colors and
letting the guest mesa clamp it if it wants.
On the other hand, if we clamp it on the host, as we do now, then the
guest mesa only has clamped values to work with, which needless to say,
can't be "unclamped".
Unfortunaly, this fix doesn't work for the GL ES backend, because in
GL ES the colors read with glReadPixels are always clamped.

Probably for some time now the generics are moved from index 0-31
to 9-40, and this doesn't fit the masks we were using, so use
64 bit masks.
Apparently this only triggered an assert and didn't lead to further
failures when the assertion was not enabled so that the CTS didin't
catch this.
We could also use 32 bit masks and shift the index by 9, but if
this would get us into trouble we ever decide to switch the
PIPE_CAP_TGSI_TEXCOORD in mesa/virgl.
Fixes a number of piglits from the glsl-1.10 set that otherwise trigger
