stable version 0.1.x.
* scdaemon.texi (Card applications): New section.
* scdaemon.c (main): New option --disable-application.
* app.c (is_app_allowed): New.
(select_application): Use it to check for disabled applications.
* ccid-driver.h (CCID_DRIVER_ERR_ABORTED): New.
* ccid-driver.c (ccid_open_reader): Support the stable 0.1 version
of libusb.
(ccid_get_atr): Handle short messages.
* apdu.c (my_rapdu_get_status): Implemented.
* certreqgen.c (get_parameter_uint, create_request): Create
an extension for key usage when requested.
* gpgsm.c (main): Install emergency_cleanup also as an atexit
handler.
* verify.c (gpgsm_verify): Removed the separate error code
handling for KSBA. We use shared error codes anyway.
* export.c (export_p12): Removed debugging code.
* encrypt.c (gpgsm_encrypt): Put the session key in to secure memory.
(gpgsm_agent_genkey, gpgsm_agent_istrusted)
(gpgsm_agent_marktrusted, gpgsm_agent_havekey)
(gpgsm_agent_passwd): Add new arg CTRL and changed all callers.
(start_agent): New arg CTRL. Send progress item when starting a
new agent.
* sign.c (gpgsm_get_default_cert, get_default_signer): New arg
CTRL to be passed down to the agent function.
* decrypt.c (prepare_decryption): Ditto.
* certreqgen.c (proc_parameters, read_parameters): Ditto.
* certcheck.c (gpgsm_create_cms_signature): Ditto.
Note, that I have not yet achieved to generate a cert with the
subjectAltName using OpenSSL. It seems that openssl requires the
email address to be part of the subject DN (subjectAltName=email:copy)
but this is something we don't want to do.
* server.c (cmd_genkey): New.
* certreqgen.c: New. The parameter handling code has been taken
from gnupg/g10/keygen.c version 1.0.6.
* call-agent.c (gpgsm_agent_genkey): New.
