Make the transition to script-genereated GLX code easier.

Move "handcoded" ARB_transpose_matrix functions to their own file.  From
here on out, such handcoded functions should go in a file named
indirect_FOO.c, where "FOO" is some logical name for the functionality
(e.g., part of the extension name, etc.).
