Merge #10825: net: set regtest JSON-RPC port to 18443 to avoid conflict with testnet 18332

ce3baa193 changed regtest RPCport to 18443 to avoid conflict with testnet 18332 (Ferdinando M. Ametrano)

Pull request description:

  using the same JSON-RPC default port for both testnet and regtest prevents running both at the same time on the same machine. Since RPCport=P2Pport-1 for both mainnet and testnet, and regtest P2Pport being 18444, 18443 is proposed for regtest RPCport

  Documentation has been updated (or created where missing); manpages doc/man/bitcoin*.1 could include information for regtest too
