Actually we could handles this different by not putting a comment tag
into the s-expression, however this requires more code and at other
places we already return "(none)" instead of an empty comment.
The second fix is more or less a cosmetic thing to get better error
messages in case the underlying read system call returns an error.

Requirements for a passphrase to protect a private key and for a

pattern file can be used to replace the other passphrase constraints
options and thus we don't need to duplicate them for symmetric
encryption.

This implements the gpg-agent side for checking whether a new passphrase

Performing a checkpin inquiry is only allowed if the passphrase
constraints are enforced. setup_enforced_constraints sends necessary
options and translated strings to pinentry.
The patch also merges 557ddbde32 et

but without changing all functions names to gpgrt. Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error. This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions. Tested builds
against 1.27 and 1.40-beta.
Note that g13-syshelp does not anymore default to --verbose because
that can now be enabled in /etc/gnupg/g13-syshelp.conf.

Using the keygrip instead of the identifier works on OpenPGP cards and
thus we use that to make sure that we are working on the right card.
For other cards we better don't do that to avoid regressions. Those
other cards are also usually provided and do not allow to
self-generate the keys.
Note that old versions of the code (gpg 1.4) used the fingerprint as
additional check but that was eventually removed and now that we use
the keygrip all over the place, it is best to use this to identify a
key.
