* Implementation of "chunked framing" according to RFC6242 for Netconf 1.1.

Browse source 
* First hello is 1.0 EOM framing, then successing rpc is chunked framing
  * See
    * [Netconf framing](https://github.com/clicon/clixon/issues/50), and
    * [Clixon does not switch to chunked framing after NETCONF 1.1 is negotiated](https://github.com/clicon/clixon/issues/314)
* C:
  * Moved netconf framing code from netconf application to clixon lib
* Test:
  * New expecteof_netconf and adjusted other expect scripts to handle NETCONF 1.1 framing
