everything that sounds like lucipam renamed to sasl2auth
- this is because that plugin had originally nothing to do with PAM and
therefore the name was misleading (whether the PAM at the backend will
be used in fact depends on how the saslauthd service is configured)
- options of SASL server created on sasl2auth plugin are now fully
and only configurable through /etc/sasl2/luci.conf file which can
be used to change the backend from PAM to e.g. a SASL native database,
Kerberos or any other mechanism that can be found by sasl libraries
(/usr/lib[64]/sasl2/ or similar path)
- according to
http://www.postfix.org/SASL_README.html#server_cyrus_location,
/ect/sasl2 location for searching SASL server configuration was
introduced as of version 2.1.22 so requirement in spec file changed
accordingly
- removed unneeded "factory" function from sasl2auth plugin as this only
passed its arguments to main object's constructor and this can be done
directly
