[libvirt] [PATCH 1/4] tests: schema: Add possibility to validate individual files

[Peter Krempa]

Sometimes it may be desired to validate individual files against a
schema. Refactor the data structures to unify them and introduce a new
macro DO_TEST_FILE(schema, xmlfile) which will test the XML file against
the given schema file.
