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

remove send lock (#334)
* remove send lock

When mplex receives data it will block until a reader has processed the
data. Thus, when a large message is received, such as a gossipsub
subscription table, all of mplex will be blocked until all reading is
finished.

However, if at the same time a `dial` to establish a gossipsub send
connection is ongoing, that `dial` will be blocked because mplex is no
longer reading data - specifically, it might indeed be the connection
that's processing the previous data that is waiting for a send
connection.

There are other problems with the current code:
* If an exception is raised, it is not necessarily raised for the same
connection as `p.sendConn`, so resetting `p.sendConn` in the exception
handling is wrong
* `p.isConnected` is checked before taking the lock - thus, if it
returns false, a new dial will be started. If a new task enters `send`
before dial is finished, it will also determine `p.isConnected` is
false, then get stuck on the lock - when the previous task finishes and
releases the lock, the new task will _also_ dial and thus reset
`p.sendConn` causing a leak.

* prefer existing connection

simplifies flow

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
