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.

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.

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.

The glib macro for g_atomic_pointer_get() uses typeof() with an
intermediate variable, resulting in a stray compiler warning if the
argument uses `const` as the intermediate variable also ends up being
const. Use an extra non-const intermediate variable to work around this.

When the compiler does not have support for the __error__ attribute,
fallback to use the GCC posion pragma, which works on both gcc and
clang. It ha the advantage of being more portable and working at the
preprocessor level, which means is not affected by symbol redirection
due to builtin conversion or stack-protector remapping, at the cost of
worse diagnostics.

The function argument where the cast is applied is volatile void *,
use the same type on the cast.

While these usages are not supposed to be security sensitive, it's still
best to avoid the usage altogether so that we do not need to think about
it. Add a taint macro so that this does not regress in the future.
