Implemented the idle "spawn" in LmBlockingResolver.

In order to simulate the asynchronous API of LmResolver the synchronous
LmBlockingResolver runs in an idle callback. That means the lm_resolver_lookup
call will return just as it does in the asynchronous version and instead the
result will come through the given callback.
