gpg: Extend the --quick-gen-key command.

* g10/keygen.c (quickgen_set_para): Add arg 'use'.
(quick_generate_keypair): Add args 'algostr', 'usagestr', and
'expirestr'.  Implement primary only key mode.
(parse_algo_usage_expire): Set NBITS for the default algo.
* g10/gpg.c (main): Extend --quick-gen-key command.
