Add tests for it.

Add tests.

Fix tests to use random assigned OS ports instead of predefined.
* Fix flaky tests in testasyncstream.
* 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.
Fix of the following bug:
In case of multiple accept headers with same preference
`preferredContentType` used to select the first match within content types
provided by the application. For example, if user specifies accept headers
`application/octet-stream, application/json` and application provides
`application/json, application/octet-stream`, `application/octet-stream`
will be returned, and that is a bug.
Now the procedure returns the most suitable match according
to the application preferences.
* Add more accept() call error handlers.
Fix issue when HTTP server silently stops accepting new connections.
Remove unneeded MacOS syscall to disable SIG_PIPE on socket, we already mask this signal in process.
* User `if` instead `case` because constants are actually variables.
* Fix mistypes.
* Do not use case for posix constants.
* Fix Linux compilation error.
Fix async streams issue with replacing state.
Add `closing` states to HTTP's server connection, request and bodyrw.
Fix Http server cancellation leaks.
