Prepare for new checkpoint APIs by describing the XML that will represent a checkpoint. The checkpoint XML is modeled heavily after virDomainSnapshotPtr. See the docs for more details. Add testsuite coverage for some minimal uses of the XML (bare minimum, the sample from html, and a full dumpxml, and some counter-examples that should fail schema validation). Although use of the REDEFINE flag will require the <domain> subelement to be present, it is easier for most of the tests to provide counterpart output produced with the NO_DOMAIN flag (particularly since synthesizing a valid <domain> during testing is not trivial).
