Split constants out into their own file. Hide the
values in named types in a struct, so that when
using the gldebug tag we can attach extra
information (such as the name of a uniform and
attribute).

No tests yet. I am working on a gltest package that can
create a windowless context on a variety of platforms for
testing GL code, but given current priorities it is a
couple of weeks away.

Various versions of these headers cause harmless (but frustrating)
compile errors, e.g. *C.char being swapped out in some function
definitions for *C.uchar. To simplify builds, importing the
headers from khronos.org.

Compiling a binary with "-tags gldebug" will add log
tracing to each GL function call. This is the best I
can offer in lieu of of real error handling.
A colleague has accused me of Aspect-oriented
programming. The wikipedia article on the topic lost
me in the first paragraph, so just for the record,
this was inspired by the way the cover tool rewrites
source code.

A new set of bindings, as none of the existing open source
ones meet all the desired criteria:
- just ES 2/3, no deprecated/wider interfaces
- no hiding of GL functions behind higher-level interfaces
- no exported use of C types
- no other library dependencies
- no exported use of unsafe.Pointer
- use Go slices for passing arrays
Function stubs were generated from the gl.xml spec file,
however there were enough special cases (and few enough
functions in the ES spec) that it was easier to construct
most of this file by hand rather than complete a generator
script. So it is not included in this CL.
