Mark the unreachable lines in compat_{,p}threads and workqueue
...
These are all related to failures from functions that either can't
fail as we call them, or where we cannot provoke failure.

Check for EINTR correctly on windows
...
(even though these are nonblocking calls and EINTR shouldn't be possible).
Also, log what error we're seing if drain_fn fails.

Fix possible infinite loop on pipe/sock_drain()
...
If the returned value of read/recv is 0 (meaning EOF), we'll end up in an
infinite loop (active wait) until something is written on the pipe which is
not really what we want here especially because those functions are called
from the main thread.

Isolate the "socketpair or a pipe" logic for alerting main thread
...
This way we can use the linux eventfd extension where available.
Using EVFILT_USER on the BSDs will be a teeny bit trickier, and will
require libevent hacking.

Split threading-related code out of compat.c

Also, re-enable the #if'd out condition-variable code.
Work queues are going to make us hack on all of this stuff a bit more
closely, so it might not be a terrible idea to make it easier to hack.
