* Disable HTTP/1.1 pipeline support for HTTP/S server by default.
Add tests.
* Fix tests according to new behavior.
Fix tests to use random assigned OS ports instead of predefined.
* Fix flaky tests in testasyncstream.
* move `Future[T]` into its own module along with some basic accessors

This PR moves all compile-time configuration to a single module,
simplifying documentation and access to these features.
Upcomfing features may be enabled either individually, or through a new
`chronosPreviewV4` catch-all designed to allow code to be prepared for
increased strictness in future chronos releases.
`-d:chronosDebug` may be used to enable the existing debugging helpers
together.
* ioselectors_epoll() refactoring.
* ioselectors_kqueue() refactoring.
* ioselectors_poll() initial refactor.
* Remove `s.count` because it inconsistent and not used in `chronos`.
* Remove Windows version of select() engine.
* Add ability to switch event queue engine via `asyncEventEngine` command line option.
* Make it possible to switch between engines.
* Fix epoll regression.
* Fix poll() engine issues.
* Address review comments.
* Add proper trick.
* Address review comments.
* Bump version to 3.1.0.
* Allow passing in trustAnchors to newTLSClientAsyncStream
* Store X509TrustAnchors in a memory-secure, but memory-friendly way
* Remove forgotten import
* Change some waitFor to await in tests; add comment about trustAnchors reuse
* Remove use of result in newTrustAnchorStore
Remove `result` usage.
Remove cast[T] usage.
Add more helpers for TransportAddress checks.
Add isGlobal() helper to check if TransportAddress is globally accessed IP address.
Add tests.
Add more tests for sub.
Add TransportAddress.toHex().
Allow `type = proc(...) {.async.}` for pre-declaring async callback
types - in this case, the macro applies the correct transformation to
the return type and adds the appropriate exception / gcsafe annotations
* Address #329.
* Refactor AsyncStreamReader/Writer `state` helper functions.
Fix some compilation warnings in `debugutils`.
Add multiple writes into test to check consistency.
* Fix Linux issue.
Fix warnings.
* Fix some warnings messages.
* More warning fixes.
* Address review comments.
Fix MacOS issues.
* More warning fixes.
* More Windows specific fixes.

Refactor to remove `result`.
Improve performance and behavior of timer to string procedure.
Add tests.
Add IndexError crash test for Linux/MacOS.
Add Sentinel version of fix.
Add GetQueuedCompletionStatusEx() support for Windows, which allows to capture more then one event in single `poll()` call.
* AsyncEventQueue (AsyncEventBus replacement) initial commit.
* Add closeWait() and remove assertion test.
* Fix "possible" memory leak.
* Add limits to AsyncEventQueue[T].
Add tests for AsyncEventQueue[T] limits.

* More debugging echoes in exception handlers.
* Convert suspected test into async procedure.
* Make multiple consumers test async.
* Remove GC debugging.
* Disable added tests.
* Disable AsyncEventQueue tests to confirm that this is an issue.
* Enable all the tests.
* 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.
The socket selector holds a `seq` of per-descriptor data. When a reader
is registered, a pointer to a seq item is stored - when the `seq` grows,
this pointer becomes dangling and causes crashes like
https://github.com/status-im/nimbus-eth2/issues/3521.
It turns out that there already exist two mechanisms for passing user
data around - this PR simply removes one of them, saving on memory usage
and removing the need to store pointers to the `seq` data that become
dangling on resize.
`nim doc --project --index:on chronos.nim` was failing with the following error:
/path/to/nim-chronos/chronos/transports/common.nim(519, 21) Error: '*' expected
...which in turned caused errors in all files that import this one.
Now the entire docs can be built successfully, with only a few warnings.
Fixes#186.
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.
