In `async` functions, a closure environment is created for variables
that cross an await boundary - this closure environment is kept in
memory for the lifetime of the associated future - this means that
although _some_ variables are no longer used, they still take up memory
for a long time.
In Nimbus, message validation is processed in batches meaning the future
of an incoming gossip message stays around for quite a while - this
leads to memory consumption peaks of 100-200 mb when there are many
attestations in the pipeline.
To avoid excessive memory usage, it's generally better to move non-async
code into proc's such that the variables therein can be released earlier
- this includes the many hidden variables introduced by macro and
template expansion (ie chronicles that does expensive exception
handling)

* 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)
