A drawback of this auto-switching is that the PIN cache of the cards

* scd/app-openpgp.c (do_reselect): Clear PIN cache flags.

It seems that the verification status of the OpenPGP app on a Yubikey
is reset on a select. We need to reflect this in our cache to avoid a
"Bad PIN" error on computing a signature.

This option is currently only useful for Yubikeys and basically
ignored with other cards. Its use is
SERIALNO --all
LEARN --force --multi
which will then print keypairinfo and other stuff for the OpenPGP and
PIV application of a Yubikey. Scute is going to use this to allow
using certificates from OpenPGP and PIV at the same time.

"DISCONNECT" command always works well without this option.

This has been tested with gpgsm and RSA keys. For ECC keys only

because gpgsm does not yet support ECC certificates and thus we can't
