First off, as late as ES 3.2, GetInternalformat only supports
RENDERBUFFER and 2DMS(_ARRAY) targets.
Secondly, the _mesa_has_ext helpers are very accurate... a little too
accurate, some might say. If we only show an extension in compat
profiles because core profiles have the functionality guaranteed, they
will return false. Fix these to either check for a core profile
explicitly, or to a different-but-identical extension available in core
profile.

Clean up misrepetitions ('if if', 'the the' etc) found throughout the
comments. This has been done manually, after grepping
case-insensitively for duplicate if, is, the, then, do, for, an,
plus a few other typos corrected in fly-by
v2:
* proper commit message and non-joke title;
* replace two 'as is' followed by 'is' to 'as-is'.
v3:
* 'a integer' => 'an integer' and similar (originally spotted by
Jason Ekstrand, I fixed a few other similar ones while at it)

For ES 3.0 NUM_SAMPLE_COUNTS spec points that some formats will be
always zero. But on ES 3.1 can be different to zero.
The current code is correctly checking exactly against version 3.0,
but the comment only mentions 3.0 spec. It is clearer mentioning both.

The comment clarifies that the driver is called only to try to get
a preferred internalformat, and that it was already checked if the
format is supported or not.

It discards out the targets and internalformats that explicitly
mention (per-spec) that doesn't support filter types other than
NEAREST or NEAREST_MIPMAP_NEAREST. Those are:
* Texture buffers target
* Multisample targets
* Any integer internalformat
For the case of multisample targets, it was used the existing method
_mesa_target_allows_setting_sampler_parameter. This would scalate
better in the future if new targets appear that doesn't allow to
set sampler parameters.
We consider RENDERBUFFER to support LINEAR filters, because although
it doesn't support this filter for sampling, you can set LINEAR
on a blit operation using glBlitFramebuffer.

It is implemented combining the values returned by calls to the 32-bit
query _mesa_GetInternalformati32v.
The main reason is simplicity. The other option would be C&P how we
implemented the support of GL_MAX_{WIDTH/HEIGHT/DEPTH} and GL_SAMPLES.
Additionally, doing this way, we avoid adding checks on the code, as
are done by the call to the query itself.
MAX_COMBINED_DIMENSIONS is the only pname pointed on the spec of
needing a 64-bit query. We handle that possibility by packing the
returning value on the two first 32-bit integers of params. This
would work on the 32-bit query as far as the value is not greater
that INT_MAX. On the 64-bit query wrapper we unpack those values
in order to get the final value.

Implemented by calling GetIntegerv with the equivalent pname and
handling individually the exceptions related to dimensions.
All those pnames are used to get the maximum value for each dimension
of the given target. The only difference between this calls and
calling GetInteger with pnames like GL_MAX_TEXTURE_SIZE,
GL_MAX_3D_TEXTURE_SIZE, etc is that GetInternalformat allows to
specify a internalformat.
But at this moment, there is no reason to think that the values would
be different based on the internalformat. The spec already take that
into account, using these specific pnames as example on Issue 7 of
arb_internalformat_query2 spec.
So this seems like a hook to allow to return different values based on
the internalformat in the future.
It is worth to note that the piglit test associated to those pnames
are checking the returned values of GetInternalformat against the
values returned by GetInteger, and the test is passing with NVIDIA
proprietary drivers.

"IMAGE_FORMAT_COMPATIBILITY_TYPE: The matching criteria use for the
resource when used as an image textures is returned in
<params>. This is equivalent to calling GetTexParameter with <value>
set to IMAGE_FORMAT_COMPATIBILITY_TYPE."
Current implementation of GetTexParameter for this case returns a
field of a texture object, so the support of this pname was
implemented creating a temporal texture object and returning that
value.
It is worth to mention that right now that field is not reassigned
after initialization. So it is somehow hardcoded. An alternative
option would be return that value. That doesn't seems really scalable
though.

From arb_internalformat_query2 spec:
" If <internalformat> is not color-renderable, depth-renderable, or

does not support multiple samples (ie other than
TEXTURE_2D_MULTISAMPLE, TEXTURE_2D_MULTISAMPLE_ARRAY, or
RENDERBUFFER), <params> is not modified."
So there are cases where the buffer should not be modified. As the
64-bit query is a wrapper over the 32-bit query, we can't just copy
the values to the equivalent 32-bit buffer, as that would fail if the
original params contained values greater that INT_MAX. So we need to
copy-back only the values that got modified by the 32-bit query. We do
that by filling the temporal buffer by negatives, as the 32-bit query
should not return negative values ever.

The goal is to extend the GetInternalformativ query to implement the
ARB_internalformat_query2 specification, keeping the behaviour defined
by the ARB_internalformat_query if ARB_internalformat_query2 is not
supported.
v2: Don't require ARB_internalformat_query when profile is GLES3.

From the ARB_internalformat_query2 spec:
"If the particular <target> and <internalformat> combination do not make
sense, or if a particular type of <target> is not supported by the
implementation the "unsupported" answer should be given. This is not an
error."
This function checks if the <target> is supported by the implementation.
v2: Allow RENDERBUFFER targets also on GLES 3 profiles.

The ARB_internalformat_query2 specification defines which is the
reponse best representing "not supported" or "not applicable" for
each <pname>.
Queries for unsupported features, targets, internalformats, combinations
of: target and internalformat, target and pname, pname and internalformat,
do not return an error but the corresponding 'unsupported' response.
We will use that response as the default answer.
For SAMPLES the 'unsupported' response is to not modify the 'params' buffer.

At this point, all uses have been replaced by the more general hook
QueryInternalFormat, introduced by ARB_internalformat_query2.

Currently, the number of integers returned in the response to
GetInternalFormativ is being tracked by a 'count' variable.
This is so only the modified elements from the temporary buffer are copied into
the original user buffer.
However, with the introduction of ARB_internalformat_query2, keeping track
of 'count' would complicate the code a lot, considering the high number of
queries.
So, we propose to forget about tracking count, and move all the 16 elements
in the temporary buffer, back to the user buffer (clamped to user buffer size
of course). This is basically a trade-off between performance and code clarity.

The restriction on multisampled integer texture formats only applies to
GLES 3.0, so don't apply it to GLES 3.1 contexts. This fixes a slew of
dEQP-GLES31.functional.state_query.internal_format.*
tests, which now all pass.
