Thus allow passing the same file descriptor as the source of multiple
stdios.

fix#1074
When fd is closed and new one (with the same number) is opened inside
kqueue/epoll/port loop's callback - stale events might invoke callbacks
on wrong watchers.
Check if watcher was changed after invocation and invalidate all events
with the same fd.
fix#826
Check that a timer that is started from a check handle gets picked up
correctly, i.e. that it influences the timeout used in the next tick
of the event loop.
This commit fixes two closely related integer overflow bugs:
* Timers with a timeout > INT_MAX cause uv__next_timeout() to return
a negative value.
* Timers with very large timeouts (close or equal to ULLONG_MAX) run on
the next tick.
In both cases, clamp the values to prevent the overflow from happening.

It makes the assumption that if you try to write to a localhost socket
often enough, eventually its send queue will fill up - which doesn't
happen if the machine it's running on is fast enough.
uv_guess_handle is currently squelching both fifo and all
sockets on to the UV_NAMED_PIPE type. Rather than treating
all sockets as UV_NAMED_PIPE, use getsockopt() and
getsockaddr() to determine if the socket is an AF_UNIX
stream (in which case return UV_NAMED_PIPE), or an AF_INET
stream (in which case return UV_TCP), or an AF_INET datagram
socket (in which case return UV_UDP).
Additionally, currently all other file descriptor types are
squelched to the UV_FILE type. Instead, only file descriptors
that are marked as regular files are treated as UV_FILE. All
other types (such as directories, character and block devices)
are now treated as UV_UNKNOWN_HANDLE.
Wake up the event loop with uv_async_send() when a request is cancelled.
Ensures the done_cb is run on the next tick of the event loop.
Not sending a wakeup signal results in the done_cb not getting called until
another request completes, which may be a long time coming when it's the only
request in the queue or when other requests are executing long-running jobs.
Fixes#669.
Allows for running the event loop in 3 modes:
* default: loop runs until the refcount drops to zero
* once: poll for events only once and block until one is handled
* nowait: poll for events only once but don't block if there are
no pending events
Fix a rather obscure bug where the event loop stalls when an I/O watcher is
stopped while an artificial event, generated with uv__io_feed(), is pending.
This can be used in conjuction with uv_run_once() to poll in one thread and run
the event loop's event callbacks in another.
Useful for embedding libuv's event loop in another event loop.
Currently, `uv_spawn` will set `environ` to the value of `options.env`, even if
`options.env` is `NULL`. This results in child processes for whom `environ ==
NULL`, which can cause a variety of unexpected issues.

Demonstrates temporary event loop stall with uv-unix. The issue is that pending
requests aren't processed until the next event (I/O, timeout, etc.) happens.
