egl/dri2: non-shared glapi cleanups

For a while now we require shared glapi for EGL, thus we can drop a
few bits from the olden days. Namely - dlopen(NULL...) is not possible,
error out at build stage if so and drop the guard around dlclose().

egl/dri2: glFlush is not optional, treat it as such

The documentation is clear - one must glFlush the old context on
eglMakeCurrent. Thus keeping it optional is not something we should be
doing. Furthermore if we cannot get the entry point we're likely having
a broken setup/stack.

mesa_glinterop: allow building without X and related headers

This commit effectively reverts c10dcb2ce837922c6ee4e191e6d6202098a5ee10
and fixes the typedef redefinition which inspired it.

In order to prevent requiring X packages at build time earlier commit
forward declared the required X/GLX typedefs. Since that approach
introduced typedef redefinition (a C11 feature) it was reverted.

To avoid the redefinition while _not_ mandating X and related headers
forward declare the structs and use those through the header.

As anyone uses the mesa interop header they ensure that the X (or others
in terms of EGL) headers are included, which ensures that everything is
resolved within the compilation unit.

glx: Perform check for valid fbconfig against proper X-Screen.

Commit cf804b4455fac9e585b3600a8318caaced9c23de
('glx: fix crash with bad fbconfig') introduced a check
in glXCreateNewContext() if the given config is a valid

Unfortunately the check always checks the given config against
the fbconfigs of the DefaultScreen(dpy), instead of the
actual X-Screen specified in the config config->screen.

This leads to failure whenever a GL context is created
on a non-DefaultScreen(dpy), e.g., on X-Screen 1 of
a multi-x-screen setup, where the default screen is
typically 0.

st/glsl_to_tgsi: disable on-the-fly peephole for 64-bit operations

This optimization is incorrect with 64-bit operations, because the

the source operands.

A lucky coincidence of how the writemask test works resulted in this
optimization basically never being applied anyway. As far as I can tell,
the only case where it would (incorrectly) have been applied is something
like

    dvec2 d;
    float x = (float)d.y;
