- new functionality: ev_set_userdata, ev_userdata,
- ev_unloop and ev_loop wrongly used a global variable to exit loops,
instead of using a per-loop variable (bug caught by accident...).
- the ev_set_io_collect_interval interpretation has changed.
- add new functionality: ev_set_userdata, ev_userdata,
ev_set_invoke_pending_cb, ev_set_loop_release_cb,
ev_invoke_pending, together with a long example about thread
locking.
- ev_unloop and ev_loop wrongly used a global variable to exit loops,
instead of using a per-loop variable (bug caught by accident...).
- add ev_timer_remaining (as requested by Denis F. Latypoff).
- add ev_loop_depth.
- calling ev_unloop in fork/prepare watchers will no longer poll
for new events.
- Denis F. Latypoff corrected many typos in example code snippets.
- the ev_set_io_collect_interval interpretation has changed.
- honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
check that the syscall number is available before trying to
use it (reported by ry@tinyclouds).

slightly higher accuracy.
- properly declare ev_loop_verify and ev_now_update even when
!EV_MULTIPLICITY.
- implement ev_loop_depth.
- do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
- support EV_MINIMAL==2 for a reduced API.
- actually 0-initialise struct sigaction when installing signals.

This sounds a bit complicated, see L<Be smart about timeouts>, above, for a
usage example.
=item ev_timer_remaining (loop, ev_timer *)
Returns the remaining time until a timer fires. If the timer is active,
then this time is relative to the current event loop time, otherwise it's
the timeout value currently configured.
That is, after an C<ev_timer_set (w, 5, 7)>, C<ev_timer_remaining> returns
C<5>. When the timer is started and one second passes, C<ev_timer_remain>
will return C<4>. When the timer expires and is restarted, it will return
roughly C<7> (likely slightly less as callback invocation takes some time,
too), and so on.
=item ev_tstamp repeat [read-write]
The current C<repeat> value. Will be used each time the watcher times out
