sbin/unwind : resolver.c unwind.h
Log message:
Since resolve() switched to a callback mechanism all uw_resolver objects
pass through resolve() and either asr_resolve_done() or
ub_resolve_done().
With that we can pull resolver_ref() and resolver_unref() into those
functions to make the reference counting easier.
Only check_resolver is special since it needs to refcount the to be
checked resolver. But the resolver doing the actual work is
automatically refcounted by resolve() and *_resolve_done().
One last piece of the puzzle is to track the uw_resolver object in
cb_data so that the *_resolve_done() functions have access to it.
This also allowes us to remove the ad-hoc passing of the resolver in
query_imsg. Since the callback functions all need access to the
resolver that did the work we pass it in as first argument.
OK otto
