scd: Make app_genkey and supporting ISO function more flexible.
* scd/app.c (app_genkey): Add arg keytype. * scd/app-common.h (struct app_ctx_s): Fitto for the genkey member. * scd/command.c (cmd_genkey): Adjust for change. * scd/iso7816.c (do_generate_keypair): Replace arg read_only by new args p1 and p2. (iso7816_read_public_key): Adjust for this. (iso7816_generate_keypair): Add new args p1 and p2. * scd/app-openpgp.c (do_genkey): Adjust for changes.
The OpenPGP card creates keys according to parameters read from a data
object. Other cards we are about to implement require a direct
specification of the requested keytype. This patch implements the
required changes.
