glapi: Enable ES compatibility mode

Ages ago Chia-I added an ES compatibility flag to several of the various
generator scripts.  The intention was to bridge differences between ES
and desktop in Mesa builds without ES.  It doesn't appear that it has
ever been used.  Recent changes to static_dispatch status of several ES1
functions caused problems in desktop-only, non-shared-glapi builds.
Enabling the ES compatibility mode appears to fix these build problems.

This is kind of a duct tape solution to this problem.  As I mentioned in
the cover letter for the series that triggered the build problem, I
would like to make some major changes to the generator architecture and
the XML.  The whole point of the proposed architecture changes is to
better handle the differences between desktop GL and ES.  I think duct
tape is okay for now.

glapi: Remove support for "short string" mode

C89 has a fairly short minimum-maximum string length.  To support
compilers limited by the C89 limits, this script had a mode where it
would generate a character array instead of a giant string.  These were
functionally the same, but the code generated for the character array is
HUGE and difficult to read.

As far as I can tell, nothing in Mesa uses '-m short' any more.  The

stopped using '-m short' when we stopped tracking the generated files.

st/mesa: overhaul texture / sample swizzle code

Previously we only examined the GL_DEPTH_MODE state to determine the
sampler view swizzle for depth textures.  Now we also consider the
texture base format for color textures too.

The basic idea is if we're sampling from a RGB texture we always
want to get A=1, even if the actual hardware format might be RGBA.
We had assumed that the texture's A values were always one since that's
what Mesa's texstore code does.  But if we render to the RGBA texture,
the A values might not be 1.  Subsequent sampling didn't return the
right values.

Now we examine the user-specified texture base format vs. the actual
gallium format to determine the right swizzle.

Fixes several fbo-blending-formats, fbo-clear-formats and fbo-tex-rgbx
