Erik Skultety ae06048bf5 virlog: Introduce virLog{Get,Set}DefaultOutput 
These helpers will manage the log destination defaults (fetch/set). The reason
for this is to stay consistent with the current daemon's behaviour with respect
to /etc/libvirt/<daemon>.conf file, since both assignment of an empty string
or not setting the log output variable at all trigger the daemon's decision on
the default log destination which depends on whether the daemon runs daemonized
or not.
This patch also changes the logic of the selection of the default
logging output compared to how it is done now. The main difference though is
that we should only really care if we're running daemonized or not, disregarding
the fact of (not) having a TTY completely (introduced by commit eba36a3878) as
that should be of the libvirtd's parent concern (what FD it will pass to it).

 Before:
 if (godaemon || !hasTTY):
     if (journald):
         use journald

 if (godaemon):
     if (privileged):
         use SYSCONFIG/libvirtd.log
     else:
         use XDG_CONFIG_HOME/libvirtd.log
 else:
     use stderr

 After:
 if (godaemon):
     if (journald):
         use journald

     else:
         if (privileged):
             use SYSCONFIG/libvirtd.log
         else:
             use XDG_CONFIG_HOME/libvirtd.log
 else:
     use stderr

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
