* src/conf/domain_conf.h: Add new member "target" to struct
_virDomainDeviceDriveAddress.
* src/conf/domain_conf.c: Parse and format "target"
* Lots of tests (.xml) in tests/domainsnapshotxml2xmlout,
tests/qemuxml2argvdata, tests/qemuxml2xmloutdata, and
tests/vmx2xmldata/ are modified for newly introduced
attribute "target" for address of "drive" type.
The RNG for <seclabel> was too strict - if it was present, then it
had to have sub-elements, even if those didn't make sense for the
given attributes. Also, we didn't have any tests of <seclabel>
parsing or XML output.
In this patch, I added more parsing tests than output tests (since
the output populates and/or reorders fields not present in certain
inputs). Making the RNG reliable is a precursor to using <seclabel>
variants in more places in the XML in later patches.
