b9ebdbcc64 uloop: fix corner cases with recursive uloop_run calls 
With multiple recursive calls to uloop_run, the callback for the same fd
can be run multiple times from different levels in the stack.
Prevent this by tracking the stack of uloop_fd callbacks and buffering new
incoming events for fds already on the stack.

ae40b66130 uloop: rework event processing, fix use-after-free issues 
Recursive calls to uloop_run() need to process already fetched events
first, before running kqueue/epoll to get more.

The state of cur_fd/cur_nfds and the event list needs to be maintained
properly to prevent accidental running of events pointing at deleted
uloop_fd structs.

17f4e41ecb uloop: improve edge trigger reliability on mac os x 
Sometimes after re-arming a fd, an initial event for reads is not generated,
even though there is data pending. Work around this by making the trigger
level-triggered first, then switching to edge trigger after processing the first
event.
