It's not possible to call portdbapi.xmatch in an asynchronous context, since the internal synchronous aux_get call would trigger event loop recursion. Therefore, an async_xmatch method is desirable.

Deprecate unused xmatch method parameters. Use the compat_coroutine decorator for backward compatibility with python2.7 (via PEP 342 enhanced generators).
