c9a10be5ba Introduce incoming buffer size limit 
- incoming buffered network requests limited to 150,000 bytes
  which I believe is ample for a genuine client
- if exceeded, the connection is dropped
- raise outgoing data limit for RPC connections to 5 MB - expect
  sessions calls can be long and connection is implicitly trusted
- similarly raise incoming buffered data limit to 5 MB for RPC
  connections

c08ade5861 Add session logging facility 
Move session logging code to protocol.py from electrum_rpc.py
Use it for periodic logging controlled by envvar LOG_SESSIONS
For each session, track sent transaction stats and show that
per-session instead of errors

6aef79461f Don't shut down block processor by cancellation 
The block processor needs to be able to close cleanly, and not
mid-block.  In order to be able to yield whilst processing blocks
we cannot forcefully close its coroutine with a cancellation.

59244cc24e Move bulk of FS flush code to db.py 
More logically belongs there.
Have servers use the flushed DB height not the block processor's height.
Get all headers only from disk.

42c00d32d2 Rewrite lib/jsonrpc.py to be a useful client too 
Use for an improved electrumx_rpc.py, so it now handles responses spread
over several packets.  Also added a timeout of 5 seconds.

98fd178c62 Make mempool truly asynchronous 
Mempool updates happen in parallel asynchronously to processing of
new blocks once caught up.  This means that, e.g., during the initial
slow mempool download incoming blocks can be processed and communicated
to clients without waiting for the downloaded mempool transaction
analysis to complete.  From a client's point of view the server won't
be seen as lagging.

063a5469cc Move mempool to be with BlockServer 
BlockProcessor doesn't really need a mempool; mempools are
only useful for servers.
Set first_sync before flushing, so it goes into DB state.
Start servers immediately on catchup; mempool fills asynchronously.

f17ad2ddf4 Put notifications on the session queue 
This keeps the network in-order and means slow clients get slow
notifications, which seems fairer.
