mem usage cleanups for pubsub (#564)
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)

* move seen table salt to floodsub, use there as well
* shorten seen table salt to size of hash
* avoid unnecessary memory allocations and copies in a few places
* factor out message scoring
* avoid reencoding outgoing message for every peer
* keep checking validators until reject (in case there's both reject and
ignore)
* `readOnce` avoids `readExactly` overhead for single-byte read
* genericAssign -> assign2

Don't allow concurrent pushdata (#444)

fix channels not being reset (#439)
* fix channels not being reset

silly for loop..

* allow only one concurrent read
* fix mplex test race condition
* add some bufferstream eof tests

* deadlock, lost data and hung channel fixes

* prevent concurrent `reset` calls
* reset LPChannel when read is cancelled (since data is lost)

* ensure that all data is returned before EOF is returned
* keep running activity monitor for half-closed channels (or they never
get closed)

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

mplex fixes (#362)
* remove almost-empty types module
* lock when writing message (that's the only place the lock matters, and
only when the message is > max msg size)
* logging updates (log in consistent order, makes reading logs easier)
* raise EOF from readExactly only if no bytes have been read (to signal
that _no_ bytes were lost)

refactor bufferstream to use a queue (#346)
This change modifies how the backpressure algorithm in bufferstream
works - in particular, instead of working byte-by-byte, it will now work
seq-by-seq.

When data arrives, it usually does so in packets - in the current
bufferstream, the packet is read then split into bytes which are fed one
by one to the bufferstream. On the reading side, the bytes are popped of
the bufferstream, again byte by byte, to satisfy `readOnce` requests -
this introduces a lot of synchronization traffic because the checks for
full buffer and for async event handling must be done for every byte.

In this PR, a queue of length 1 is used instead - this means there will
at most exist one "packet" in `pushTo`, one in the queue and one in the
slush buffer that is used to store incomplete reads.

* avoid byte-by-byte copy to buffer, with synchronization in-between
* reuse AsyncQueue synchronization logic instead of rolling own
* avoid writeHandler callback - implement `write` method instead
* simplify EOF signalling by only setting EOF flag in queue reader (and
reset)
* remove BufferStream pipes (unused)
* fixes drainBuffer deadlock when drain is called from within read loop
and thus blocks draining
* fix lpchannel init order
