channel close race and deadlock fixes (#368)
* channel close race and deadlock fixes

* remove send lock, write chunks in one go
* push some of half-closed implementation to BufferStream
* fix some hangs where LPChannel readers and writers would not always
wake up
* simplify lazy channels
* fix close happening more than once in some orderings
* reenable connection tracking tests
* close channels first on mplex close such that consumers can read bytes

A notable difference is that BufferedStream is no longer considered EOF
until someone has actually read the EOF marker.

* docs, simplification

use stream directly in chronosstream (#163)
* use stream directly in chronosstream

for now, chronos.AsyncStream is not used to provide any features on top
of chronos.Stream, so in order to simplify the code, chronosstream can
be used directly.

In particular, the exception handling is broken in the current
chronosstream - opening and closing the stream is simplified this way as
well.

A future implementation that actually takes advantage of the AsyncStream
features would wrap AsyncStream instead as a separate lpstream
implementation, leaving this one as-is.

* work around chronos exception type issue
