Comparing JSON docs using strcmp is simple, but is not flexible as it is sensitive to whitespace used in the doc generation. When comparing objects it may also be desirable to treat the existance of keys in the actual object but not expected object as non-fatal. Introduce a virJSONStringCompare function which takes two strings representing expected and actual JSON docs and then does a DOM comparison. Signed-off-by: Daniel P.

Test suites using the port allocator don't want to have different behaviour depending on whether a port is in use on the host. Add a VIR_PORT_ALLOCATOR_SKIP_BIND_CHECK which test suites can use to skip the bind() test. The port allocator will thus only track ports in use by the test suite process itself. This is fine when using the port allocator to generate guest configs which won't actually be launched Signed-off-by: Daniel P.
