This is quite handy for gpg-card's APDU command and avoids that we

(do_getattr): Use app_get_dispserialno.
--
This patch gets us back to a unique serial number for cards and
provides a stable serial number as printed for Yubikeys.
Because we use a slightly different serial number now for Yubikeys and
cards only supporting OpenPGP card we need to come up with another
change so that the version number of OpenPGP serial numbers are
ignored when comparing card serial numbers. This is so that existing
stub keys of gpg-agent will continue to work.

This is helpful so that callers do not need to parse the key for this
basic information. Use "scd readkey --info-only" to return the info
status line instead of the key material; using just --info returns the
info in addition to the key material.

This has been tested with a D-Trust card featuring 3072 bit keys.
Note that non-repudiation key for a qualified signature does not yet
work because we do not yet support rsaPSS padding. Thus a gpgsm
--learn shows a couple of Bad Signature errors for this key.

This change does away with encrypting and decrypting the cached PIN in
the agent. There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent. This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.
