This should be used also for other chardev devices.
Easily done for parallels, consoles, and channel... IOW: Others that
call virDomainChrDefParseXML which calls virDomainChrDefNew(xmlopt) in
order to set up privateData.
Less easy for smartcard, rng, and redirdev's. Unfortunately the PRIVATE
stuff is based off a virDomainChrDefPtr while the smartcard, rng, and
redirdev's each use their own virDomain*DefPtr that includes a
virDomainChrSourceDefPtr (for RNG) or virDomainChrSourceDef (for
smartcard and redirdev).
BTW: The hotplug code for smartcard, rng, and redirdev isn't
implemented... Follow qemuDomainAttachChrDevice callers and you'll see
separate calls for redirdev, rng, and smartcard. Clearly I misread all
the various permutations...
Looks like I'll need to either implement privateData for
virDomainCharSourceDefPtr or duplicate what's done for ChrDef for
redevdir, rng, and smartcard. Neither is appealing...
