pubkey: Move sexp parsing for gcry_pk_getkey to the modules.
* cipher/pubkey-util.c: New. (_gcry_pk_util_get_nbits): New. Based on code from gcry_pk_genkey. (_gcry_pk_util_get_rsa_use_e): Ditto. * cipher/pubkey.c (gcry_pk_genkey): Strip most code and pass. * cipher/rsa.c (rsa_generate): Remove args ALGO, NBITS and EVALUE. Call new fucntions to get these values. * cipher/dsa.c (dsa_generate): Remove args ALGO, NBITS and EVALUE. Call _gcry_pk_util_get_nbits to get nbits. Always parse genparms. * cipher/elgamal.c (elg_generate): Ditto. * cipher/ecc.c (ecc_generate): Ditto. Signed-off-by: Werner Koch <wk@gnupg.org>
