Add primegen() to the testcrypt API.

Browse Source 
I just found I wanted to generate a prime with particular properties,
and I knew PuTTY's prime generator could manage it, so it was easier
to add this function to testcrypt for occasional manual use than to
look for another prime-generator with the same feature set!

I've wrapped the function so as to remove the three progress-
reporting parameters.
