Merge #10812: [utils] Allow bitcoin-cli's -rpcconnect option to be used with square brackets

Browse Source 
5c643241e [utils] allow square brackets for ipv6 addresses in bitcoin-cli (John Newbery)
fe4fabaf1 [refactor] move SplitHostPort() into utilstrencodings (John Newbery)

Pull request description:

  bitcoin-cli's `-rpcconnect` can accept ipv6 addresses (as long as the libevent version is new enough), but fails to parse ipv6 with square brackets. This PR makes `bitcoin-cli` parse ipv6 in square brackets correctly.

  `bitcoin-cli -rpcconnect=[::1] <command>`

  should now be equivalent to

  `bitcoin-cli -rpcconnect=::1 <command>`

  This is useful so the `bitcoin-cli` option can now be in the same format as the `bitcoind` option.

  Doesn't include tests. I have a branch that fully tests `bitcoin-cli`, but that's queued behind several intermediate PRs.

  - first commit moves `SplitHostPort()` from libbitcoin_common into libbitcoin_util
  - second commit adds proper ipv6 parsing to bitcoin-cli
