Patch enables ES2 extension that utilizes existing ES3 functionality.
Changes make all the subtests to run and pass in WebGL conformance
test 'webgl-draw-buffers' when running Chrome on OpenGL ES, also
Piglit test 'draw_buffers_gles2' passes.
v2: remove unused boolean (Ilia Mirkin)
v3: proper error checking for invalid values (Chad Versace)
v4: run error check explicitly for ES2 and ES3 (Kenneth Graunke)

The following preparations were made in texstate.c and texstate.h to
better facilitate the BindTextureUnit function:
Dylan Noblesmith:
mesa: add _mesa_get_tex_unit()
mesa: factor out _mesa_max_tex_unit()
This is about to appear in a lot more places, so
reduce boilerplate copy paste.
add _mesa_get_tex_unit_err() checking getter function
Reduce boilerplate across files.
Laura Ekstrand:
Made note of why BindTextureUnit should throw GL_INVALID_OPERATION if the unit is out of range.
Added assert(unit > 0) to _mesa_get_tex_unit.

Tested with piglit gl-1.0-beginend-coverage (it now also crashes on
debug builds.)

This fixes several MSVC warnings like:
warning C4273: 'glClearColorx' : inconsistent dll linkage
In fact, we should avoid using `declspec(dllexport)` altogether, and use
exclusively the .DEF instead, which gives more precise control of which
symbols must be exported, but all the public GL/GLES headers practically
force us to pick between `declspec(dllexport)` or
`declspec(dllimport)`.

The GL side of this extension just provides an accessor via glGetIntegerv for
the value of GL_CONTEXT_RELEASE_BEHAVIOR so it is trivial to implement. There
is a constant on the context for the value of the enum which is initialised to
GL_CONTEXT_RELEASE_BEHAVIOR_FLUSH. The extension is always enabled because it
doesn't need any driver interaction to retrieve the value.
If the value of the enum is anything but FLUSH then _mesa_make_current will
now refrain from calling _mesa_flush. This should only affect drivers that
explicitly change the enum to a non-default value.

Adding this makes 'make check' catch failures introduced from

Implement the mesa parts of ARB_clip_control.
So far no driver enables this.
v3:
Restrict getting clip control state to the availability
of ARB_clip_control.
Move to transformation state.
Handle clip control state with the GL_TRANSFORM_BIT.
Move _FrontBit update into state.c.

In commit 32f2fd1c5d, several calls to
_mesa_calloc(x) were replaced with calls to calloc(1, x). This is strictly
equivalent to what the code was doing previously.
But for cases where "x" involves multiplication, now that we are explicitly
using the two-argument calloc, we can do one step better and replace:
calloc(1, A * B);
with:
calloc(A, B);
The advantage of the latter is that calloc will detect any overflow that would
have resulted from the multiplication and will fail the allocation, (whereas
the former would return a small allocation). So this fix can change
potentially exploitable buffer overruns into segmentation faults.
