Automatically enable systemd journal logging
Probe to see if the systemd journal is accessible, and if so enable logging to the journal by default, rather than stderr (current default under systemd).
Previously 'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug output to stderr, now it send debug output to the journal.
Only use the journal by default if running in daemon mode, or if stdin is _not_ a tty. This should make libvirtd launched from systemd use the journal, but preserve the old behavior in most situations.
Makes sense.
Thinking about it a bit more, should we be checking if stderr, rather than stdin, is a ttty? That is, if you run 'libvirtd </dev/null' from a terminal, don't you still want output to the stderr tty?
But the libvirtd > out 2>&1 is going to stop working which is a lot more useful then anything stdin related. - Cole
