* 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
* `CLICON_RESTCONF_PATH` is now obsolete for sure
* Instead if you use fgci/nginx:
* Use `restconf/fcgi-socket`
* Ensure `<CLICON_FEATURE>clixon-restconf:fcgi</CLICON_FEATURE>` is set
* Added default values to restconf-config and save fcgi-socket-path in memory
- Changed logic on how to find clixon_restconf in pseudo plugin
- Removed ==== in constants to avoid conflict with git merge
- Remove assert
- Added fuzzing for netconf
- Fix event exit bug (set to new counter, dont increment)
- Changed default CI to be restconf=native instead of fcgi1~
- Tests:
- Change to same wait backend and restconf commands
- Change default restconf protocol from http to https
* clixon_restconf daemon is installed in /usr/local/sbin (as clixon_backend), instead of /www-data
* `configure --with-wwwdir=<dir>` remains but only applies to fcgi socket and log
* New option `CLICON_RESTCONF_INSTALL_DIR` is set to where clixon_restconf is installed, with default `/usr/local/sbin/`
* Restconf drop privileges user is defined by `CLICON_RESTCONF_USER`
* `configure --with-wwwuser=<user>` is removed
* clixon_restconf drop of privileges is defined by `CLICON_RESTCONF_PRIVILEGES` option
* New clixon-restconf@2020-05-20.yang revision
* Added: restconf `log-destination`
- Stricter CLICON_BACKEND_RESTCONF_PROCESS :
- if set, restconf daemon queries backend for its config
- if not set, restconf daemon reads its config from main config file
