Currently, any driver that does not support the ARB_compatibility
extension will fail on GL3.1 context creation if the application does
not request the forward-compatiblity flag.
Restore the original check which changes mesa_api to API_OPENGL_CORE,
only when:
- GL3.1 is requested, without the forward-compatiblity flag.
- driver does not support ARB_compatibility - as deduced by
max_gl_compat_version.
Fixes: a0c8b49284 ("mesa: enable OpenGL 3.1 with ARB_compatibility")
v2:
- Improve commit log (Emil).
- Provide a correct explanation on the features documentation (Ian).

Unfortunately Adreno A4xx hardware returns incorrect results with the

offsets, including on cube maps which normally never have offsets.

This extension is effectively a backport of GLES3's internalformat
handling to GLES 1/2. It guarantees that sized internalformats specified
for textures and renderbuffers have at least the specified size stored.
That's a pretty minimal requirement, so I think it can be dummy_true and
exposed as a standard in Mesa.
As a side effect, it also allows GL_RGB565 to be specified as a texture
format, not just as a renderbuffer. Mesa had previously been allowing 565
textures, which angered DEQP in the absence of this extension being
exposed.
v2: Allow 2101010rev with sized internalformats even on GLES3, citing the
extension spec. Extend extension checks for GLES2 contexts exposing
with texture_float, texture_half_float, and texture_rg.
v3: Fix ALPHA/LUMINANCE/LUMINANCE_ALPHA error checking (GLES3 CTS
failures)
v4: Mark GL_RGB10 non-color-renderable on ES, fix A/L/LA errors on GLES2
with float formats.

This uses all the existing code to calculate lod values for mip linear
filtering. Though we'll have to disable the simplifications (if we know some
parts of the lod calculation won't actually matter for filtering purposes due
to mip clamps etc.). For better or worse, we'll also disable lod calculation
hacks (mostly should make a difference for cube maps) always - the issue with
per-pixel lod being difficult is mostly because we then have different mipmaps
needed for the actual texel fetch, which isn't a problem with lodq.
We still use approximation for the log2 - for that reason I believe the float
part of the lod is only accurate to about 4-5 bits (and one bit less with 1d
textures actually) which is hopefully good enough (though d3d10 technically
requires 6 bits - could use quadratic interpolation instead of linear to get
8 bits or so).
Since lodq requires unclamped lod, we also have to move some sampler key
calculations to texture sampling code - even if we know we're going to access
mipmap 0 we still have to calculate lod and apply lod_bias for lodq.
Passes piglit ARB_texture_query_lod tests (after having fixed the test).

This was implemented since forever, but not enabled.
It passes all piglit tests except one, arb_pipeline_statistics_query-frag.
The reason is that the test (for drawing a 10x10 rect) expects between
100 and 150 pixel shader invocations. But since llvmpipe counts this with
4x4 granularity (and due to the rect being 2 tris) we end up with 224
invocations. I believe however what llvmpipe is doing violates neither the
spirit nor the letter of the spec (our fragment shader granularity really
is 4x4 pixels, albeit we will bail out early on 2x2 or 4x2 (the latter
if AVX is available) granularity), the spec allows to count additional
invocations due to implementation reasons.
