[libvirt] RFC move logging initialization earlier in libvirtd

[Dave Allan]

I noticed yesterday that logging gets initialized fairly far into the 
libvirtd startup process, so messages generated during server startup 
don't get logged to the same sinks that will be used for the rest of the 
life of the daemon.  I'd like to explore moving the logging startup to 
an earlier point.  Has this idea been explored previously?
