sm: Rework the PKCS#12 parser to support DFN issued keys.
* sm/minip12.c (struct p12_parse_ctx_s): New.  Use this instead of
passing several parameters to most functions.
(parse_pag_data): Factor things out to  ...
parse_shrouded_key_bag): new.
(parse_cert_bag): New.
(parse_bag_data): New.
(p12_parse): Setup the parse context.
--

To support newer pkcs#12 files like those issued by the DFN we need to
support another ordering of data elements.  This rework reflects the
P12 data structure a bit better than our old ad-hoc hacks.  Tests could
only be done with the certificate parts and not the encrypted private
keys.

agent,ssh: Fix for make not-inserted OpenPGP.3 keys available for SSH.
* agent/command-ssh.c (ssh_send_available_keys):  Do not bump
key_counter for ignored keys.  Also use opt.debug instead of
opt.verbose and fix a memory leak.
--

The error shown by "ssh-add -l" before this fix was:
  error fetching identities: incomplete messag

agent: New option --no-user-trustlist and --sys-trustlist-name.
* agent/gpg-agent.c (oNoUserTrustlist,oSysTrustlistName): New.
(opts): Add new option names.
(parse_rereadable_options): Parse options.
(finalize_rereadable_options): Reset allow-mark-trusted for the new

* agent/agent.h (opt): Add fields no_user_trustlist and
sys_trustlist_name.
* agent/trustlist.c (make_sys_trustlist_name): New.
(read_one_trustfile): Use here.
(read_trustfiles): Use here.  Implement --no-user-trustlist.
--

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.

g10: Fix garbled status messages in NOTATION_DATA
* g10/cpr.c (write_status_text_and_buffer): Fix off-by-one
--

Depending on the escaping and line wrapping the computed remaining
buffer length could be wrong.  Fixed by always using a break to
terminate the escape detection loop.  Might have happened for all
status lines which may wrap.

This is similar to parse_debug_flags but does not support specifying a

re-use them for other purposes.

This allows me to create qualified signatures using my Telesec card.
There is of course more work to do but this is the first step.

Note: The design of the FID cache needs to be reconsidered.  Until
that the lookup here has been disabled.  The do_sign code should be
revamped to be similar to what we do in app-p15.
