Automatically determine the number of DH bits in the TLS handshake.

Instead of using a default value of 1024, check the OpenPGP key and
determine an appropriate number of DH bits to use, (using GnuTLS
functions made for this).  Document this new default behavior.

* plugins.d/mandos-client.c (safe_string): New function.
  (init_gnutls_global): If not specified, determine the number of DH
                        bits to use, based on the OpenPGP key.
* plugins.d/mandos-client.xml (OPTIONS): Document this new default of
                                         the --dh-bits option.

Thanks to Andreas Fischer <af@bantuX.org> for reporting this issue.
