This includes a small refactoring to use a new enum (workqueue_reply_t)
for the return values instead of just ints.

This avoids a conflict with a macro decl from libevent 1.x.

Fixes bug 16867; bug not in any released Tor.

We don't want to accept any work after one of our worker functions has
returned WQ_RPL_SHUTDOWN. This testcase currently fails, because we do
not actually stop any of the worker threads.

Needs changes file, documentation, test integration, more tests.
