- Rename all _create() functions --> _init()
- Rename all _delete() functions --> _stop()
- Watchers are automatically started, except
- Timer watchers are automatically started by uev_run()
- Allow I/O watchers to watch either EV_READ/EV_WRITE or both events
- Extend callbacks with a received events field
- Remove calloc()/free(), let user handle this
- Make event has-a context when initializing it => simplifies API
- Internal uev_watcher_*() API mostly handles epoll stop/start

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.

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.

- Cleanup code
- Further polish on total size using black magic
- Remove OpenBSD queue.h, code simplied so much now it's not needed anymore.
Instead we can rely on the standard GNU/Linux sys/queue.h (old BSD copy)

- Remove double book keeping, the kernel does all the heavy lifting now
- Trim the amount of #includes
- Use LIST_ instead of TAILQ_ now that we no longer handle timers ourselves

This is a major refactor of the original design by Flemming Madsen. It
converts the library timers from poll() to timerfd, which at the same
time also unifies the file and timer watchers into one design. The idea
is to also add signalfd to the mix later on.
Also a couple of hundred kilobytes smaller, although size a secondary
goal. The primary goal is to further simplify the internal design and
to continuously strive to employ modern APIs.
