More multi-version support

Minor fix to idl_output: switch from None to '' to alow split to work
Add 'InReleases' member to verify node is valid within a list of releases.
Add 'releases' member to IDLVersionMap class for easier search.
Remove stale code and build ordered list of requested releases in AST
Remove release member from CGen object, and pass into functions
Move release tracking from C prototype to C header generator
Update generator tests.
Added golden files to verify the C generator is correct

NOTE:  This is work in progress.  The header emitted using
--release=X should be correct and has been tested to generate
exactly what we have today, however --range=X,Y does not yet
generate what we need.

TEST= python generator.py
