Add base class for generators

Add base class for generators

This CL is the first step towards alowing multiple generators
with a single driver to simplify the use of the generator.
It removes old built-in in idl_c_header.py, and replaces it with
several golden files to verify output is unchanged.
It renames the old 'version' option to 'release' to disambiguate
between a RELEASE name such as M14, and an interface VERSION such
as 1.0.

Removes the 'M14' hack which as added to the source code to force
release M14 to be generated.

what is the significance of count?  The number of registered generators that
should not run?  Sort of confusing.
