Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions.

NB: *Use* of this infrastructure is so far only skeletal.

Fixed a few typos and minor issues along the way.

Minor "to do" items are identified in the source code with "TODO..." comments.
Major items to do:
* Use the new versioning infrastructure to identify all errors specific to
- profile
- extension
- version
- stage
* Add semantics for all new grammar (1.2 through 4.3)
* Replace the preprocessor with a better one.
* Verify/fix thread safety of the parse context.
