Add preprocessor support for parsing doubles.

Add double support to the flex stage.

Put in some of the basic double supported needed in the front end.

Add generic support for version numbers in the preprocessor, and the core, compatibility, and es profiles.

1) Improve error recovery from arrays sized with a non constant.  2) Add double vectors to the lexer.  3) Default to vertex shaders for unrecognized file name suffixes.

Also fix issue where the keyword "shared" conflicts with the layout qualifier identifier "shared" by allowing the keyword in the layout qualifier identifier list.

Also add buffer and shared keywords and grammar, which brings the grammar up to 4.3.

N.B. There is a problem for "shared": it is both a keyword (as a storage qualifier) and an identifier (for layouts).

Remove the pack/unpack languages and bring grammar up from 1.1 to 4.2 and fix the affected 1.1 productions and semantics to still work correctly for 1.1 shaders.

For 4.2, largely, it is only the grammar that is working.  Productions and semantics are mostly missing.  Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.

The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
