Introduce a vtable system for prime generation.

Browse Source 
The functions primegen() and primegen_add_progress_phase() are gone.
In their place is a small vtable system with two methods corresponding
to them, plus the usual admin of allocating and freeing contexts.

This API change is the starting point for being able to drop in
different prime generation algorithms at run time in response to user
configuration.
