Avoid `break` in problematic test.

Fix closeWait() calls to use noCancelWait() predicate.
Adding sleep to flaky MacOS test.

Address review comments.
* Refactor chronos trackers to be more simple.
* Refactor trackers.
Add HTTP server trackers.
Refactor HTTP main processing loop.
* Compatibility fixes.
Add checkLeaks().
* Fix posix test issue.
* Add httpdebug module which introduces HTTP connection dumping helpers.
Add tests for it.
* Recover and deprecate old version of Trackers.
* Make public iterators to iterate over all tracker counters available.
Fix asynctests to use public iterators instead private one.
* Tentative fix for the HTTP client connection state assertion failures
I've traced the problem to a HTTP connection being closed while there
are outstanding requests that still go through the motions (the crash
occurs when a requests reaches its `finish` processing step, but it
was already put in a Closed state by the connection that owns it).
* Use distinct error exception instead of cancellation error.

When calling the HTTP `send` / `open` functions, `acquireConnection` is
called to obtain a connection in state `Ready`. In the next code block,
the connection state is advanced to `RequestHeadersSending`. However,
returning from chronos `async` procs yields control, similar to `await`.
This means that a connection may be added to the pool in `Ready` state,
and then a different `acquireConnection` call may obtain a second ref.
Introducing a new `Acquired` state ensures consistency in this case.
No tests added due to this being scheduler dependent; ran manual tests
by adding a `doAssert item.state != HttpClientConnectionState.Acquired`
between `if not(isNil(conn)):` and `return conn`. Eventually, the assert
got hit after several hours of repeated tests, confirming the edge case
to be solved by applying this fix.
Not sure if it is by design that returning from an `async` proc yields.
Even if it's not, this should solve current HTTP issues in nimbus-eth2.
