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.
