Log Message:

aio-posix: Unregister fd from ctx epoll when removing fd_handler.
Cleaning the events will cause aio_epoll_update to unregister the fd.
Otherwise, the fd is kept registered until it is destroyed.

Log Message:
-----------
aio-posix: Fix concurrent aio_poll/set_fd_handler.
It is possible for an io_poll callback to be concurrently executed along
with an aio_set_fd_handlers. This can cause all sorts of problems, like
a NULL callback or a bad opaque pointer.
This changes set_fd_handlers so that it no longer modify existing handlers
entries and instead, always insert those after having proper initialisation.
