Switch from old-style ASSERT macro to new-style ASSERT_EQ,... macros.
Using new-style macros makes it easier to debug test failures
Fixes: https://github.com/libuv/libuv/issues/2974
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.
While most users will likely typically call uv_close in their
uv_shutdown callback, some callers (notable nodejs) do not always do
so. This can result in libuv keeping the loop active, even though there
are no outstanding reqs left to handle.
This bug was added in 80f2f826bf90b84e659321c0b7fd8af419acb85e, where
the premise of that commit appears to have simply been incorrect, as
demonstrated by the added test.
