P2P and network changes
-----------------------
- Normally local transactions are broadcast to all connected peers with
which we do transaction relay. Now, for the `sendrawtransaction` RPC
this behavior can be changed to only do the broadcast via the Tor or
I2P networks. A new boolean option `-privatebroadcast` has been added
to enable this behavior. This improves the privacy of the transaction
originator in two aspects:
1. Their IP address (and thus geolocation) is never known to the
recipients.
2. If the originator sends two otherwise unrelated transactions, they
will not be linkable. This is because a separate connection is used
for broadcasting each transaction. (#29415)
