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: 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);`

test: fix test-ipc tests

A couple of ipc tests failures where undercover by the previous commit.

- In `ipc-heavy-traffic-deadlock-bug`, `uv_shutdown` can fail with
`UV_ENOTCONN`. Allow it.
- `ipc_closed_handle` was failing consistently on `Centos6` because the
first large write was completed in just one syscall. Also, there were
issues with the lifetime of the `uv_write_t` requests. Refactor the
test so it passes consistently on `Centos6` while fixing the
`uv_write_t` issues.

test,unix: fix race in test runner

The test runner inserted a 250 ms delay to give helper processes time to
settle. That's intrinsically race-y and caused tests to intermittently
fail on platforms like AIX.

Instead of a fixed delay, pass a file descriptor to the helper process
and wait until it closes the descriptor. That way we know for sure the
process has started.

Incidentally, this change reduces the running time of the test suite
from 112 to 26 seconds on my machine.
