This patch backports some changes from master but also adds the
Display-S/N tracking.

(opts): Add new option names.

repalce "allow_include" by "systrust" and adjust callers.
--
With the global options we can now avoid that a user changes the
Root-CA trust by editing the trustlist.txt. However, to implement
this we need a new option so that we don't need to rely on some magic
like --no-allow-mark-trusted has been put into a force section.
The second option makes system administration easier as it allows to
keep the trustlist in a non-distributed file.

Actually we could handles this different by not putting a comment tag

The second fix is more or less a cosmetic thing to get better error

Requirements for a passphrase to protect a private key and for a
passphrase used for symmetric encryption are different. Thus a
the use of a different pattern file will be useful. Note that 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

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.
