04f194aa8a uloop: fix deleting pending fd events on uloop_fd_del 
When a fd gets deleted internally due to errors, fd->registered gets set
to false before events are moved to the staging array.
This leads to pending events not getting cleared properly when the fd
user finally calls uloop_fd_del.
Fix this by moving the check down and always checking for pending
events.

510e4956e5 uloop: Fix incorrect timeout 
uloop timeouts are calculated based on a time value that was fetched
before any callbacks were executed. Hence, the next timeout is off by
the time the callback execution took which can lead to strange side
effects.

Fix this by calculating the next timeout based on a fresh time value.

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.
