* CLI reconnects to backend if backend restarts with a warning

Browse source 
* Note that edits to the candidate database or locks will be lost
  * To force the CLI to exit if backend restarts, undef `PROTO_RESTART_RECONNECT`
  * This is an effect of the fix of [Broken pipe error seen in client (cli) when backend restarts and CLICON_SOCK is recreated](https://github.com/clicon/clixon/issues/312), the CLI behavior on backend restart is changed.
* Added `eof` parameter to `clicon_rpc()` and `clicon_rpc1()` and error handling modified
