In `stream.readLoop`, a finished `Future` was left in `transp.reader`
if there was an error in `resumeRead`. Set it to `nil` as well.

We can check at compile-time that at least one parameter is passed
* clean up closure environment explicitly in some callbacks to release
memory earlier
* Fix `or` should not create future with OwnCancelSchedule flag set.
* Fix `CancelledError` missing from raises list when both futures has empty raises list.
* Fix macros tests.

Fix by checking for `void` before trying to access `raises`
* Add more specific accept() exceptions raised.
Add some refactoring to HTTP server code.
* Refactor acceptLoop.
* Print GC statistics in every failing test.
* Try to disable failing tests.
Features:
* Exception effects / raises for async procedures helping you write more
efficient leak-free code
* Cross-thread notification mechanism for suitable building channels,
queues and other multithreaded primitives
* Async process I/O
* IPv6 dual stack support
* HTTP middleware support alloing multiple services to share a single
http server
* A new [documentation web
site](https://status-im.github.io/nim-chronos/) covering the basics,
with several simple examples for getting started
* Implicit returns, support for `results.?` and other conveniences
* Rate limiter
* Revamped cancellation support with more control over the cancellation
process
* Efficiency improvements with `lent` and `sink`
See the [porting](https://status-im.github.io/nim-chronos/porting.html)
guides for porting code from earlier chronos releases (as well as
asyncdispatch)
Feature flags allow consumers of chronos to target versions with and
without certain features via compile-time selection. The first feature
flag added is for raise tracking support.
* simplify `closeWait` implementations
* remove redundant cancellation callbacks
* use `noCancel` to avoid forgetting the right future flags
* add a few missing raises trackers
* enforce `OwnCancelSchedule` on manually created futures that don't raise `CancelledError`
* ensure cancellations don't reach internal futures
Because the callback types were used explicitly in some consumers of
chronos, the change of type introduces a backwards incompatibility
preventing a smooth transition to v4 for code that doesn't uses
`raises`.
This PR restores backwards compatibility at the expense of introducing a
new type with a potentially ugly name - that said, there is already
precedence for using numbered names to provide new error handling
strategy in chronos.
