gpg: Find keys using mail addresses with garbage after the '>'
* kbx/keybox-search.c (blob_cmp_mail): Stop comparing at the '>'.
--

This change allows to find mail addresses like

  Joe Doe <joe@example.org> bar
  Joe Doe <joe@example.org> (comment)

using the command

   gpg  -k '<joe@example.org'

or (with syntactic sugar)

   gpg  -k '<joe@example.org>'

These UIDs are ill-formed according to gpg checks but nevertheless are
seen in the wild.

Note, that it does only work with the new keybox format.

* g10/parse-packet.c (set_packet_list_mode): Set mpi_print_mode.
* g10/misc.c (mpi_print): Do not print an extra leading zero.
--

This was in older versions possible using "--debug 4" but that was
disabled in 2.1 due to a conflict using this values also for
Libgcrypt.  Now the values are dumped either with --debug 4 or using
--list-packets along with --verbose.

Because OpenPGP only uses unsigned integers an extra leading zero will
not be printed anymore.

It is possible that an opaque MPI stores just a NULL pointer.  Take

this case because at least a length byte is required.

gpg: avoid chatter about trustdb when --quiet
* g10/trustdb.c (tdb_check_trustdb_stale): avoid log_info() when
  opt.quiet
--

gpg(1) says:

       -q, --quiet
              Try to be as quiet as possible.

While the mentions about the stale trustdb information are edifying,
they aren't necessary, and shouldn't be emitted when the user requests
--quiet.
