This patch replaces the BSD doubly linked list implementation with a
simplified homegrown version. This not only reduces the dependency on
an external "library", but also greatly simplifies licensing and gives
us a clean name space that does not intrude on users who want to use
their own version of queue.h in their application that also includes
the libuEv header file.

The semantics for timerfd in Linux is to use close() to stop,
so no need for the extra overhead with uev_timer_set().

Both cron and regular timers were closed twice on uev_exit(), first
when iterating over all watchers, next after each cb() has run in
uev_run(). This patch adds a check if a watcher is active before
attempting to stop it (again).
