This adds the mesa core + texture + fbo support for the
texture cube map array extension.
v2:
add comment to _mesa_num_tex_faces related to cube map arrays (Brian)
drop wrong comment cut-n-paste (Brian)
fix / 6 maximum check issue (Kenneth)
coalsece some array case statements (Kenneth)

Fix copy&paste error and move min levels check closer to max levels check.

Simplify the code and make it more like the other glTexImage commands.
Call _mesa_legal_texture_dimensions() to validate width, height, depth.
Call ctx->Driver.TestProxyTexImage() to make sure texture is not too large.

There are two aspects to texture image size checking:
1. Are the width, height, depth legal values (not negative, not larger
than the max size for the mipmap level, etc)?
2. Is the texture just too large to handle? For example, we might not be
able to really allocate memory for a 3D texture of maxSize x maxSize x
maxSize.
Previously, we did (1) via the ctx->Driver.TestProxyTextureImage() hook
but those tests are really device-independent. Now we do (2) via that
hook since the max texture memory and texture shape are device-dependent.
Also, (1) is now done outside the general texture parameter error checking
functions because of the special interaction with proxy textures. The
recently introduced PROXY_ERROR token is removed.
The teximage() and copyteximage() functions are bit simpler now (less
if-then nesting, etc.)

This is basically a follow-on to 1f5b1f98468d5e80be39e619ed15c422fbede8d3.
Basically, generate GL errors for ordinary invalid parameters for proxy
targets the same as for non-proxy targets. Only texture size and OOM
errors should be handled specially for proxies.
Note: This is a candidate for the stable branches.

Turns out we weren't doing any format checking before. Now check
the internal format and, in particular, make sure that unsized internal
formats aren't accepted.
Note: This is a candidate for the stable branches.

Not a real big help now, but will be useful for the
GL_ARB_texture_cube_map_array extension in the future.

This is the glTexStorage1D/2D/3D() functions. Basically do error
checking then call the driver hook to actually allocate memory.
