Dispatch error in virInitialize
Dispatch error in virInitialize

Callers that already do this anyway can be cleaned up thanks to this and the one
that does not (daemon startup) gains the benefit of the error being printed to
standard error output changing:

LIBVIRT_LOG_OUTPUTS=1:invalid libvirtd
/home/nert/dev/libvirt/upstream/build/src/libvirtd: initialisation failed

into:

LIBVIRT_LOG_OUTPUTS=1:invalid libvirtd
libvirt:  error : invalid argument: Invalid destination 'invalid' for output '1:invalid'
/home/nert/dev/libvirt/upstream/build/src/libvirtd: initialisation failed
