Message:

Allow loading of an additional PKCS #11 provider library

When using PKCS #11, it may not be desirable to add the PKCS #11 module
to be used by mod_gnutls to the system wide config, and we definitely
cannot demand it for tests.

To work around such problems, add the new configuration parameter
"GnuTLSP11Module", which may contain the path of a library to load. Note
that the value is only used if present in the base server configuration
(not a virtual host), and that the library is used in addition to
system defaults (if any).
