test: silence more valgrind warnings (#3917)

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.

process: make the 'status' parameter for exit_cb an int64_t

This means we no longer have to strip the high bit from the process exit
code on Windows, which is problematic because an unhandled SEH exception
can make a process exit with a status code that has the high bit set.

unix, windows: return error codes directly

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.

Replace `void f()` with `void f(void)`; the former means "a function

is what is actually intended: a function taking no arguments.

The first form also isn't strictly conforming ANSI/ISO C.
