[mod_gnutls] option to override GnuTLS priority
[mod_gnutls] option to override GnuTLS priority

provide option to override GnuTLS priority string
ssl.openssl.ssl-conf-cmd = ("gnutls-override" => "...")
will *entirely* replace the priority string constructed by mod_gnutls.
Admin is responsible to ensure that the override is complete.

debugging:
A non-zero value for debug.log-ssl-noise = x *in the global scope*
will cause mod_gnutls to print the GnuTLS priority string to the
error log at startup.  debug.log-ssl-noise = 0 in $SERVER["socket"]
scopes can then be used to disable runtime ssl log noise, or
debug.log-ssl-noise can be removed from the global scope after debugging
