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.
