Initial import of Flemming Madsen's LibUEvent

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
license as "New BSD License", which is wrong.  The actual license
of the project is https://en.wikipedia.org/wiki/MIT_License
