It actually uses a shared config setting from the lib (stack size) so
the function itself also belongs in the lib.

Change an argument type to bool.

Change-Id: I8be68008fcfc058cb29069102eb00497b66897a5

This is a dependency of the poller and so is needed in lib/ as well to
make it usable.

Also consolidate the type.

This allows for longer (> 1 second) sleep times reliably.

We don't have functioning thread cancellation under ASAN. Make sure our
timer threads don't sleep too long so that the tests don't time out.

Windows doesn't allow a file to be named aux, so checkout fails.

Make it possible for a looper thread function to break out of the loop

This is pointless at this stage, but makes it possible to pass

On bookworm and later, libasan reports a false positive in combination
with pthread_cleanup_push() (see [1]). Work around this by not using the
thread cleanup handler when running the asan build, and instead use a
shorter thread sleep time.

Change-Id: Ieffdc0b13f470445f1f8e1d2448c6af6d8dd68e0

Instead of having each thread sleep only a little while and then
periodically check for the shutdown flag, make them sleep longer and use
pthread_cancel() to interrupt the sleep during a shutdown in the
designated break points.

Change-Id: Ie1ef9bbfe6faaf9fa7ed163d51475f6f353309df

The only reason the wait time in timer threads is capped at 100 ms is to
catch the daemon's shutdown. Since these threads already use a
condition variable to be woken up, we can use the same condition to wake
up the threads during a shutdown, allowing for a much longer (possibly
unlimited) sleep time in timer threads.
