These three errors should probably all be changed away from

I was uncertain about the error codes too, that's why I kept
VIR_ERR_INTERNAL_ERROR as used by other functions in this file. I'd
opt for VIR_ERR_CONF_SYNTAX.
We really need to agree on a policy on which code to use for which type
of errors, write it down, then go through the code and correct
everything that's wrong. INTERNAL_ERROR is used *a lot* in XML parsing
where it obviously shouldn't be. Much of it is probably code written
before the CONFIG_UNSUPPORTED, XML_ERROR, and CONF_SYNTAX codes were
added, but I'd wager just as much is due to people writing new code who
look to the existing code for guidelines (I know I've done this a lot,
and continue to be confused about which code to use in a lot of cases -
heck, this is the first I've noticed CONF_SYNTAX, and I'm not sure when
it would be appropriate to use that vs. XML_ERROR).
