Update signature summary for the case of missing X.509 keys.

* src/verify.c (gpgme_op_verify_result): Update summary field.
--

not emit ERRSIG for a missing public key.

* Remove support for libgpgme-pth. As far as we know, this was never used,
and GnuPG is going to use our own npth in the future.
* Fix signature summary information for a missing X.509 key.
* Fix parsing of dates >= year 2038.
