This patch adds support for at/cron-like jobs that need an absolute
timer. The API supports waking up with an UEV_HUP callback event if the
wall clock changed due to NTP or user input while waiting.
- uev_cron_init()
- uev_cron_set()
- uev_cron_start()
- uev_cron_stop()
A very simple cronrun example/test program is also included.

Split libuev.c into one file per watcher type, mostly to give a better
overview and ease of maintenance, but also to help the linker.
Unfortunately this steals a few bytes when linking a full blown app, but
for apps that, e.g., only need I/O watchers and no timers the resulting
binary will be smaller. This applies to static binaries that are more
common in embedded systems.
$ size libuev.a libuev.so.1
text data bss dec hex filename
999 0 0 999 3e7 main.o (ex libuev.a)
90 0 0 90 5a io.o (ex libuev.a)
490 0 0 490 1ea timer.o (ex libuev.a)
4380 696 8 5084 13dc libuev.so.1
Also, move uev.h back to top from include/libuev/uev.h since a separate
namespace is not needed after the removal of the OpenBSD queue.h copy.

This fork is called libuev and will focus solely on embedded Linux
systems using C. Patches for other UNIX-like operating systems are
welcome.
- Remove Lua support, will not be used.
- Rename from LibUEvent to libuev where applicable
- Add project's MIT license to top of all files, as is customary
- Add a LICENSE file, as is customary
This MIT licensed code was cloned from the Mercurial repository at
Google http://code.google.com/p/libuevent/ which had mislabled the
