* refactor peerstats usages
* populate tables if missing when scoring
* streamline socket read/write hot path
This avoids some unnecessary memory copying on the hot path of noise /
mplex, as well as getting rid of a few futures - profiling shows that
this is one of the main culprits of small memory allocations, which
makes sense - this is where gossip fan-out happens.
* fewer futures (and corresponding closures) when sending lpchannel
messages
* avoid data copies when encrypting and framing noise messages
* avoid copying tuple when reading noise data (poor c codegen)
* fix setting eof flag in secure read
* write noise frames in one go
...and closing secure socket once is enough
* check that connection is not closed or eof
* don't release connection lock prematurely
* test that only valid connections can be added
* correct exception type on closed connection
* add clarifying comment
* use closeWithEOF for more stable test
* misc comments
* log stream id in buffestream asserts
* use closeWithEOF to prevent races in tests
* give some time to the remote handler to trigger
* adding more tests to make codecov happy
* handle resets properly with/without pushes/reads
* add clarifying comments
* pushEof should also not be concurrent
* move channel reset to bufferstream
this is where the action happens - lpchannel merely redefines how close
is done

To break a potential read/write deadlock, gossipsub uses an unbounded
queue for writes - when peers are too slow to process this queue, it may
end up growing without bounds causing high memory usage.
Here, we introduce a maximum write queue length after which the peer is
disconnected - the queue is generous enough that any "normal" usage
should be fine - writes that are `await`:ed are not affected, only
writes that are launched in an `asyncSpawn` task or similar.
* avoid unnecessary copy of message when there are no send observers
* release message memory earlier in gossipsub
* simplify pubsubpeer logging
* add helper to read EOF marker after closing stream (else stream stay
alive until timeout/reset)
* don't assert on empty channel message
* don't loop when writing to chronos (no need)
When messages can't be sent to peer, we try to establish a send
connection - this causes messages to stack up as more and more unsent
messages are blocked on the dial lock.
* remove dial lock
* run reconnection loop in background task
* 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
