gresolver: Add GResolver:timeout property

Browse Source 
Without a timeout, some lookup requests can go on forever, typically due
to bugs in underlying systems.

This can have particularly significant effects on the Happy Eyeballs
algorithm in `GSocketClient`, which relies on multiple name lookups as
its first step.
