test: switch to new-style ASSERT_EQ macros (#4159)
Switch from old-style ASSERT macro to new-style ASSERT_EQ,... macros.
Using new-style macros makes it easier to debug test failure

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.

poll,unix: ensure safety of rapid fd reuse
Consider the following scenario:
uv_poll_init(loop, poll, fd);
uv_poll_start(poll, UV_READABLE, cb);
// the cb gets invoked etc.
poll,unix: ensure safety of rapid fd reuse
Consider the following scenario:
uv_poll_init(loop, poll, fd);
uv_poll_start(poll, UV_READABLE, cb);
// the cb gets invoked etc.
uv_poll_stop(poll);
close(fd);
fd = allocate_new_socket(); // allocate_new_socket() is assigned the same fd by "bad luck" from the OS
// some time later:
uv_poll_init(loop, otherpoll, fd);
uv_poll_start(otherpoll, UV_READABLE, cb);
uv_close(poll); // uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.
According to documentation, "however the fd can be safely closed
immediately after a call to uv_poll_stop() or uv_close()."
Though, in this scenario, we close()'d our file descriptor, and by
bad luck we got the same file descriptor again and register a new
handle for it and start polling.
Previously that would lead to an assertion failure, if we were to
properly free the original handle via uv_close().
This commit fixes that by moving the check whether a only a single
poll handle is active to uv_poll_start() instead of the stopping
routines.
