- New flag in NOTIFY_NEW_TRANSACTION to indicate stem mode
- Stem loops detected in tx_pool.cpp
- Embargo timeout for a blackhole attack during stem phase
A newly synced Alice sends a (typically quite small) list of
txids in the local tpxool to a random peer Bob, who then uses
the existing tx relay system to send Alice any tx in his txpool
which is not in the list Alice sent
This allows RPC coming from the loopback interface to not have
to pay for service. This makes it possible to run an externally
accessible RPC server for payment while also having a local RPC
server that can be run unrestricted and payment free.

If a db resize happened, the txpool meta cursor might be stale,
and was not being renewed when necessary.
It would cause this SEGSEGV:

in mdb_cursor_get ()

During the handshake for an incoming connection, the peer id is checked against the local node's peer id only for the specific zone of the incoming peer, in order to avoid linking public addresses to tor addresses:
5d7ae2d279/src/p2p/net_node.inl (L2343)
However, on handshakes for outgoing connections, all zones are checked:
5d7ae2d279/src/p2p/net_node.inl (L1064)
If an attacker wanted to link a specific tor node to a public node, they could potentially connect to as many public nodes as possible, get themselves added to the peer whitelist, maybe stuff some more attacker-owned addresses into the greylist, then disconnect, and for any future incoming connections, respond with the tor node's id in an attempt to link the public/tor addresses.
- Finding handling function in ZMQ JSON-RPC now uses binary search
- Temporary `std::vector`s in JSON output now use `epee::span` to
prevent allocations.
- Binary -> hex in JSON output no longer allocates temporary buffer
- C++ structs -> JSON skips intermediate DOM creation, and instead
write directly to an output stream.

destroy is called from another thread, which would modify the
threads array from two threads.

Nodes remember which connections have been sent which peer addresses
and won't send it again. This causes more addresses to be sent as
the connection lifetime grows, since there is no duplication anymore,
which increases the diffusion speed of peer addresses. The whole
white list is now considered for sending, not just the most recent
seen peers. This further hardens against topology discovery, though
it will more readily send peers that have been last seen earlier
than it otherwise would. While this does save a fair amount of net
bandwidth, it makes heavy use of std::set lookups, which does bring
network_address::less up the profile, though not too aggressively.
