Note that _mesa_GetVertexAttribPointervNV() is actually
glGetVertexAttribPointerv(), which operates on the generic attributes. The
geometry shader initialization looks like arbitrary cruft to me.

Note that the MAP2 getters were missing from the implementation. Neat.
v2: Rebase on top of get.c changes.

It wasn't supported in hardware, and the comments in the code indicated no
known uses (similar to my experience on Intel) and a possible intent to remove
it.

We were holding on to this code because we were aware that NWN 1 had some
support for vertex programs -- no other linux programs I've come across would
use it (since other software also has ARB_vp or GLSL support). Only, it turns
out that NWN doesn't even give us any vertex programs. Given that we have
known issues where the extension has never been fully supported, just give up
on it.

- stopped using util_color
- reformatted to occupy less characters per line.
- used memcpy for the border color
- used pipe_color_union in the state structure
And the clear color too, though that may be an issue only with GL_RGB if it's
actually RGBA in the driver.
NOTE: This is a candidate for the stable branches.

v2: The types of st_translate_color parameters were changed to gl_color_union
and pipe_color_union as per Brian's comment.
commit a010215463 removed ES2 specific dispatch
table and remap_helper, since now we are using dispatch.h which is generated
from gl_and_es_API.xml we need to generate a matching remap_helper using the
same xml.
Note: This is a candidate for the 9.0 branch.

lp_build_rsqrt initially did not do any newton-raphson step. This meant that
precision was only ~11 bits, but this handled both input 0.0 and +infinity
correctly. It did not however handle input 1.0 accurately, and denormals
always generated infinity result.
Doing a newton-raphson step increased precision significantly (but notably
input 1.0 still doesn't give output 1.0), however this fails for inputs
0.0 and infinity (both result in NaNs).
Try to fix this up by using cmp/select but since this is all quite fishy
(and still doesn't handle denormals) disable for now. Note that even with
workarounds it should still have been faster since the fallback uses sqrt/div
(which both use the usually unpipelined and slow divider hw).
Also add some more test values to lp_test_arit and test lp_build_rcp() too while
there.
v2: based on José's feedback, avoid hacky infinity definition which doesn't
work with msvc (unfortunately using INFINITY won't cut it neither on non-c99
compilers) in lp_build_rsqrt, and while here fix up the input infinity case
too (it's disabled anyway). Only test infinity input case if we have c99,
and use float cast for calculating reference rsqrt value so we really get
what we expect.

"get_transfer + transfer_map" becomes "transfer_map".
"transfer_unmap + transfer_destroy" becomes "transfer_unmap".
transfer_map must create and return the transfer object and transfer_unmap
must destroy it.
transfer_map is successful if the returned buffer pointer is not NULL.
If transfer_map fails, the pointer to the transfer object remains unchanged
(i.e. doesn't have to be NULL).
