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.

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.

By default, we call back the driver's hook fallback function that has generic
implementations for the all the queries.
Reviewed-by: Dave Airlie <airlied@redhat.com>
This new function queries different driver parameters for a particular target
and texture format. It is basically a driver hook to support
ARB_internalformat_query2.
Since ARB_internalformat_query2 introduced several new query parameters
over ARB_internalformat_query, having one driver hook for each parameter
is no longer feasible. So this is the generic entry-point for calls
to glGetInternalFormativ and glGetInternalFormati64v.

When we find indirect indexing into an array, the current implementation
of the array spliiting optimization pass does not look further into the
expression tree. However, if the variable expression involves variable
indexing into other arrays, we can miss that these other arrays also have
variable indexing. If that happens, the pass will crash later on after
hitting an assertion put there to ensure that split arrays are in fact
always indexed via constants:
shader_runner: opt_array_splitting.cpp:296:
void ir_array_splitting_visitor::split_deref(ir_dereference**): Assertion `constant' failed.
This patch fixes the problem by letting the pass step into the variable
index expression to identify these cases properly.

There is an old if statement (dated to 2011) that prevented doing
endian swap for colorformat, in case the buffer is marked as
PIPE_USAGE_STAGING.
This is now wrong because st_ReadPixels() reads into a destination
texture that is marked with PIPE_USAGE_STAGING. Therefore, even if
the texture is rendered correctly to the monitor, when reading it
back we get unswapped/wrong values.
This patch makes the check_rgba() function in gl-1.0-readpixsanity
