Revert "glapi/es1: Don't mark core functions as static_dispatch=false"

This reverts commit f6e290f80cc6728647e9cee35546190f081197e2.

To fix the broken build.  The DRI-enabled build seems OK after reverting.
Th non-DRI/gallium build is still suffering from an unrelated issue in
the pipe-loader code.

mesa: Allow setting GL_TEXTURE_MAX_LEVEL to 0 with GL_TEXTURE_RECTANGLE.

Currently, we raise an error when doing this which breaks a conformance
test from the OpenGL samples pack. Even if this is a bit silly it is not
an error.

From http://www.opengl.org/wiki/Rectangle_Texture:

"Rectangle textures contain exactly one image; they cannot have mipmaps.
Therefore, any texture parameters that depend on LODs are irrelevant
when used with rectangle textures; attempting to set these parameters to
any value other than 0 will result in an error."

mapi: Hack around glGetInternalformativ not being hidden in GLES

This is hella ugly.  The same-named function in desktop OpenGL is
hidden, but it needs to be exposed by libGLESv2 for OpenGL ES 3.0.
There's no way to express in the XML that a function should be be hidden
in one API but exposed in another.

This won't affect any change now, but it will prevent a regression in a
