glTexStorage*D is more restrictive in supporting texture formats, especially
on GLES. Specifically, it doesn't support BGRA textures that are needed to get
any useful display, but it is needed to get immutable textures that are required
for glTextureView.
Check which formats are supported and use glTexStorage*D for these, otherwise
fall back to use glTexImage*D.

On an GL host set the sRGB blit framebuffer state explicitly to make virgl
behave like on a GLES host.
This does not correct the handing of sRGB completely, because the state
GL_FRAMEBUFFER_SRGB is not properly transmitted to the host. As a result
the piglits "blit texture linear_to_srgb * * *" flip.
Tests thatset "enable" failed before and pass now, and tests that set "disable"
now fail.
v2: - Move setting the fbo state out of the loop (Robert Tarasov)
- Use the blitter context to set and store the state, since it is only,
and currently we don't pass the state from the guest
relevant when the dst texture is SRGB, there is no need to disable it
- Just enforce that a source SRGB texture is always decoded when this could
be disabled

The TGSI FBFETCH instruction is used for implementing framebuffer-reads
when doing for instance advanced blends. It's used by both
EXT_shader_framebuffer_fetch_non_coherent and
KHR_blend_equation_advanced.
Sadly, libepoxy doesn't yet support the glFramebufferFetchBarrierEXT
function needed to implement this on top of
EXT_shader_framebuffer_fetch_non_coherent itself, so let's just implement
it on top of EXT_shader_framebuffer_fetch instead for now.
This means that we'll have slightly higher requirements for enabling
this functionality than the level of functionality we provide through it.
