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.

test: test with maximum recvmmsg buffer (#3419)

The maximum numbers receivable by the recvmmsg call is defined in
src/unix/udp.c as UV__MMSG_MAXWIDTH with the current value being 20.

Align the size of the receive buffer in the mmsg test to receive the
maximum number of UDP packets in the test.

test: move to ASSERT_NULL and ASSERT_NOT_NULL test macros

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);`
