When a handshake fails, it can fail due to timeout or destroyed
connection, in which case the connection will be, or already is,
closed, and we don't want to do it twice.
Additionally, when closing a connection directly from the top
level code, ensure the connection is gone from the m_connects
list so it won't be used again.
AFAICT this is now clean in netstat, /proc/PID/fd and print_cn.
This fixes a noisy (but harmless) exception.

The warning about spending more than one output with similar creation
time was skipped if print-ring-members was not set, and it defaults to
false, which means most people probably aren't getting this warning if
they spend correlated outputs.

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:

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.

In some contrived case, it might theoretically be the case that
destroy is called from another thread, which would modify the
threads array from two threads.
