glapi: Remove static dispatch for functions that didn't exist in 10.4

Comparing the output of

    nm libGL.so | grep ' T gl[^X]' | sed 's/.* T //'

between 10.4.7 and this commit, the only change is the removal of
glFramebufferTextureFaceARB.  This function was removed a couple commits
previously.

None of these functions are particuarly new.  If applications were not
statically linking them with 10.4.7, there's approximately zero chance
they will for 10.6.

Almost all of these functions are for GL_ARB_direct_state_access.
Since the whole DSA API wasn't statically exported (and the extension
wasn't enabled!), I think there's exactly zero chance anyone linked
against these symbols.

mesa: Remove all vestiges of glFramebufferTextureFaceARB

Mesa does not (and probably never will) support GL_ARB_geometry_shader4,
so this function will never exist.  Having a function that is
exec="skip" and offset="assign" is just weird.

There are still a couple 'exec="skip" offset="assign"' functions
remaining.  These remain because we either support GLX protocol for them
(glSampleMaskSGIS and glSamplePatternSGIS) or older DRI drivers still

egl/main: expose only core EGL functions statically

The EGL 1.3, 1.4 and 1.5 spec (as quoted below) explicitly mentions that
providing static symbols for functions provided by EGL extensions is not
portable. Considering that relatively recently we've seen a non-mesa
desktop EGL implementation, the fact that we opt for such behaviour has
gone unnoticed.

From the EGL 1.5 specification:
    For functions that are queryable with eglGetProcAddress,
    implementations may choose to also export those functions
    statically from the object libraries implementing those
    functions. However, portable clients cannot rely on this
    behavior.

To encourage devs against writing such non-portable code, let's hide the
symbols similar to the official binary driver from NVIDIA.

v2: Quote the EGL 1.5 spec, as suggested by Chad.

main: Major refactor of get_texture_for_framebuffer.

This splits off the (still) rather large chunk that is
get_texture_for_framebuffer into lots of smaller functions specialized to
service the wide variety of unique needs of *FramebufferTexture* entry points.
The result is much cleaner because, rather than having a pile of branches and
confusing conditions (like the boolean layered), the uniqueness is baked into
the entry points. The entry points know whether or not they are layered or use
a textarget.

[Fredrik: - Mention the value of <textarget> in the error message.
          - Rename check_zoffset to check_layer, and zoffset to layer.
            The zoffset parameter was renamed to layer in

softpipe: enable ARB_texture_view

Some bits were already there for texture views but some were missing.
In particular for cube map views things needed to change a bit.
For simplicity I ended up removing the separate face addr bit (just use
the z bit) - cube arrays didn't use it already, so just follow the same
logic there. (In theory using separate bits could allow for better hash
function but I don't think anyone ever did some measurements of that so
probably not worth the trouble, if we'd reintroduce it we'd certainly
wanted to use the same logic for cube arrays and cube maps.)
Also extend the seamless cube sampling to cube arrays - as there were no
piglit failures before this is apparently untested, but things now generally
work quite the same for cube textures and cube array textures so there
hopefully shouldn't be any trouble...

49 new piglits, 47 pass, 2 fail (both due to fake multisampling).

v2: incorporate Brian's feedback, add sampler view validation,
function rename, formatting fixes.

PBO for a pixel transfer operation and later on bind the same buffer
