Add new approach to properly test status XML files by supplying a full
XML file rather than generating synthetic test cases by prepending the
status header. The two tests introduced here are copies of existing
cases using the synthetic header so that current level of testing is

present in the current testing.

Reloading of the nwfilter driver is stuck waiting for a write lock, which
already has a reader (from qemuDomainCreateXML) in the critical section.
Since the reload occurs in the context of the main event loop thread,
libvirtd becomes deadlocked. The deadlock can be avoided by offloading
the reload work to a thread.

When validating a device XML config we check if user provided
alias is unique. We do this by maintaining a hash table of device
aliases as we iterated over all devices defined for the domain.
However, it may happen that what appears as two devices in domain
XML is in fact just one interface in hypervisor.  We can assume
libvirt generated aliases to be unique and thus really check user
provided ones only.
