Last version of the logging facility, now allowing to choose between No Log (default), DLF and stdout

 Do not use peer_uid and peer_gid if CSEC not defined.

Give LSF version against which we compile (we miss autoconf power here + lsf includes are not usuable at cpp time for that)

doesn't return 0.
This caused erroneous setting of serrno to EINTERNAL
instead of EDLFNOFAC when facility was not found in the database.

Make dlf_write() return 1 (one) if no log destinations were specified for
the given severity level.

Added the possibility to have global services. These are shared among threads and thus should be thread safe.

Putted YES to all c++ stuff

Add default values.
