mesa: make glTexImage, glCompressedTexImage proxy code more alike

Next up, we can combine the teximage() and compressed_teximage() functions.

mesa: rename texpal.[ch] to texcompress_cpal.[ch]

To be consistent with other files related to texture compression.

mesa: s/GLuint/gl_format/ in _mesa_compressed_format_to_glenum()

No real change here, just use the right type.

mesa: new _mesa_num_tex_faces() helper

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

mesa: make _mesa_get_proxy_tex_image() static

It's not used by any other file.

mesa: don't clear proxy image fields when regular GL error is generated

If a proxy texture call generates a regular GL error, we should not
clear the proxy image's width/height/depth/format fields.  Use a new
PROXY_ERROR token to distinguish proxy errors from regular GL errors.

mesa: fix glTexImage proxy texture error generation

When calling glTexImage() with a proxy target most error conditions should
generate a GL error.  We were erroneously doing the proxy-error behaviour
(where we zeroed-out the image's width/height/depth/format fields) in too
many places.

There's another issue with proxy textures, but that'll be fixed in the
next patch.

mesa/es: Remove redundant texture target validation

Mesa doesn't check the parameter passed to glMultiTexCoord*.  It does,
however, mask the texture value to prevent out-of-bounds writes.  This
patch will promote this non-conformant behavior to OpenGL ES 1.  I don't
think anyone will care, and the gets some silly code out of a hot path.
