* always stem local txs if configured that way (unless explicitly fluff from wallet)
this overrides current epoch behavior for txs coming in via "push-api"
rename "local" to "our" txs
* TxSource is now an enum for type safety.
When we send a txhashet archive a peer's thread is busy with sending it
and can't send other messages, eg pings. If the network connection is
slow buffer capacity 10 may be not enough, hence the peer's drop.

* Don't wait for p2p-server thread (#2917)
Currently p2p.stop() stops and wait for all peers to exit, that's
basically all we need. However we also run a TCP listener in this thread
which is blocked on `accept` most of the time. We do an attempt to stop
it but it would work only if we get an incoming connection during the
shutdown, which is a week guarantee.
This fix remove joining to p2p-server thread, it stops all peers and
makes an attempt to stop the listener.

Also 2 Arc's were replaced by one server's instance.
It is needed for p2p thread management in #2778, currently there is no point where we could store thread handles and join them because thread::join
consume the caller, which is impossible in case of Arc.

If a coinbase commitment hits a duplication and there is no transactions
to mine, it is possible that coinbase cannot be built for quite a long
time. This change tries to build coinbase with an empty key identifier
immediately in this case. The listening wallet will then use the next
available key to build a coinbase commitment, which is different from
the previous one and is unlikely to hit the duplication.
Most of the methods return nothing or bool which is used to decide if a
sender of a message should be banned or not. However underlying chain
implementation may fail so we need a way to reflect this fact in API.
Also it allows to reduce number of unwraps and makes the code more robust.

If WouldBlock error happens Stratum server drops part of a message to
read or write. This PR inroduces a worker's buffer to store partially
read message which will be completed next time. For write the existing
util function is used.
Fixes#2524
It seems that current approach stops workring after amount of parallel
connection exceeds ~500. This PR introduces an 'async' feature which
enable asyncronius, tokio based implementation of stratum server.

Default value is 8, so we allow only 4 outbound peers, unfortunately if a node is behind NAT it can't get inbound peers and it stucks with 4 peers as maximum.
This PR allows a number of outbound peers to be between min_peers and max_peers/2. Node behind NAT will eventually have just min_peers number of peers.

Currently we allocate a string in the heap per each worker check (not even
read) and clone message in write. This pr introduces a buffer which is
used for a round of workers check and remove clone in write_message.
Read optimization reduces number of allocations by factor of N (where N
is a number of workers), if N = 1 number of allocations doesn't change.

We select a peer to ask a block randomly. Peer's send channel has
capacity 10. If we need too many blocks we limit number of blocks to asks as a number of peers
* 10, which means that there is some probability (pretty high) that we
will overflow send buffer capacity.
This fix freezes a peer list (which gives also some performance boost)
and create a cycle iteraror to equally distribute requests among the
peers.
There is a risk that a peer may be disconnected while we are sending a
request to the chanel, but stricltly speaking it was possible in the old
code too, perhaps with a lower probability.
