Add io_uring support for several asynchronous file operations:
- read, write
- fsync, fdatasync
- stat, fstat, lstat
io_uring is used when the kernel is new enough, otherwise libuv simply
falls back to the thread pool.
Performance looks great; an 8x increase in throughput has been observed.
This work was sponsored by ISC, the Internet Systems Consortium.

Pass the loop to MAKE_VALGRIND_HAPPY() so it's explicit on which loop
needs to be cleaned up. Since it asserts on uv_loop_close(), need to
remove a couple of those that were being done before the call.
Cleanup where loop was assigned, so the entire test either uses loop or
uv_default_loop(). Not both.
Also take care of any reqs that may have been left uncleaned.
Moving to new style test macros will make debugging easier in case
of test failure and improve redability. This commit will replace all
ASSERT macros matching the statement:
`ASSERT(identifier (== or !=) value);`
to:
`ASSERT_(NOT_)NULL(identifier);`

Use a deterministic approach for saturating the threadpool instead of
depending on a timeout. Should help reduce the flakiness of the CI.

Saturate the thread pool before trying to post-and-cancel the work
request. Before this commit we simply posted requests in a loop,
in the (sometimes idle) hope that one would get queued up instead
of being dispatched right away.

This commit changes the libuv API to return error codes directly rather
than storing them in a loop-global field.
A code snippet like this one:
if (uv_foo(loop) < 0) {
uv_err_t err = uv_last_error(loop);
fprintf(stderr, "%s\n", uv_strerror(err));
}
Should be rewritten like this:
int err = uv_foo(loop);
if (err < 0)
fprintf(stderr, "%s\n", uv_strerror(err));
The rationale for this change is that it should make creating bindings
for other languages a lot easier: dealing with struct return values is
painful with most FFIs and often downright buggy.
The documentation in uv.h states that the status argument to the
uv_getaddrinfo() callback is either 0 or -1 but uv-unix actually
passed it the addrinfo error code. Rectify that and add a regression
test.
Fixes#754.
This changes the prototype of uv_run() from:
int uv_run(uv_loop_t* loop);
To:
int uv_run(uv_loop_t* loop, uv_run_mode mode);
Where `mode` is UV_RUN_DEFAULT, UV_RUN_ONCE or UV_RUN_NOWAIT.
Fixes#683.
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.
Bert Belder informs me the current approach where a request is immediately
cancelled, is impossible to implement on Windows.
Rework the API to always invoke the "done" callback with an UV_ECANCELED error
code.
