9bb1baef4e Add the event subsystem 
An event can be anything ranging from the exit of a process (interesting
to `wait4`) to the arrival of a blocked signal (interesting to
`sigwaitinfo`), from the completion of a file operation (interesting to
`epoll`) to the change of a file status (interesting to `inotify`).

To meet the event-related demands from various subsystems, this event
subsystem is designed to provide a set of general-purpose primitives:

* `Waiter`, `Waker`, and `WaiterQueue` are primitives to put threads
to sleep and later wake them up.
* `Event`, `Observer`, and `Notifier` are primitives to handle and
broadcast events.
* `WaiterQueueObserver` implements the common pattern of waking up
threads once some interesting events happen.

5d5e8d44ec Pass host-generated SIGPIPE to libos 
Socket-related ocalls, e.g, sendto, sendmsg and write, may cause SIGPIPE
in host. Since the ocall is called by libos, this kind of signal should
be handled in libos. We ignore SIGPIPE in host and raise the same signal
in libos if the return value of the above ocalls is EPIPE. In this way
the signal is handled by libos.
