Recent versions of gcc have started emitting warnings about the liberal

positives, let's use them as the impetus to switch to a type-safer and
arguably cleaner approach.

darwin,process: feed kevent the signal to reap children (#3893)

Since we are emulating this event, but are not using the pending_queue,
we need to make sure it is accounted for properly. Also DRY some of the
reset_timeout code here.

This was observed to cause a hang in certain rare cases, particularly on
M1 machines.

Do a bit of code cleanup too, since we do not need to initialize the
internal signal handling pipe if it will not be used.

Before this commit, cleanup was performed in various destructors.
This commit centralizes the cleanup logic, enabling the addition of
`uv_library_shutdown()`, but maintains the current observable behavior
of cleaning up when libuv is unloaded by means of `dlclose(3)`.

unix: use SA_RESTART when setting our sighandler

BSD `signal(2)` semantics make some system calls (e.g. for `write`)
restartable when interrupted by a signal handler. Use `SA_RESTART` to
enable these semantics everywhere that supports them.

This was done by libev back when we used it. In addition to being
common practice, this is required by C++ stream libraries that interpret
`EINTR` as any other error, set `badbit`, and stop writing. I've
observed this with `libstdc++` during a `std::cout.flush()` call
interrupted by `SIGCHLD`.

unix: make loops and watchers usable after fork()

Added the uv_loop_fork() API that must be called in a child process to
continue using an existing loop. Internally this calls a uv__io_fork
function for each supported platform, similar to the way
uv__platform_loop_init works.

After this call, existing and new IO, async and signal watchers will
contiue working as before on all platforms, as will the
threadpool (although any threads it was using are of course gone).

On Linux and BSDs that use kqueue, existing and new fsevent watchers
will also continue to work as expected. On OS X, though, directory
fsevents will not be able to use the optimized CoreFoundation path if
they had already been used in the parent process, instead falling back
to the kqueue path used on other BSDs.

Existing fsevent watchers will not function on AIX or SunOS. This
could be relatively easily fixed by someone with AIX knowledge in the
future, but SunOS will require some additional work to keep track if
the watchers.

A new test file, test/test-fork.c, was added to contain fork-related
tests to verify functionality in the child process.
