Refactor extra generator registration to use factories

This will allow additional information about the availability
and capabilities of extra generators to be queried without
actually creating them.

Instead of a static NewFactory() method like the main generator
factories have, use a static GetFactory() method to get a pointer to a
statically allocated extra generator factory.  This simplifies memory
management.
