* Major rewrite of event streams

* If you used old event callbacks API, you need to switch to the streams API
    * See clixon_stream.[ch]
  * Old streams API which needs to be removed include:
    * clicon_log_register_callback()
    * subscription_add() --> stream_register()
    * backend_notify() and backend_notify_xml() - use stream_notify() instead
* Example uses "NETCONF" stream instead of "ROUTING"
* Added timeout option -t for clixon_netconf - quit after max time.

* Not supported: notification, deviation, module-set-id, etc.
* Enabled by default, disable by resetting CLICON_MODULE_LIBRARY_RFC7895
* Yang 1.1 notification support (RFC 7950: Sec 7.16)
* Event stream discovery support according to RFC 5277 for netconf
* Implemented by ietf-netconf-notification.yang
* Disabled by default. Enable by setting CLICON_STREAM_DISCOVERY_RFC5277
* Event stream discovery support according to RFC 8040 for restconf

* Added stream discovery according to RFC 5277 for netconf and RFC 8040 for restconf
* Enabled by CLICON_STREAM_DISCOVERY_RFC5277 and CLICON_STREAM_DISCOVERY_RFC8040.
* Example uses "NETCONF" stream instead of "ROUTING"
* clixon_restconf and clixon_netconf now take -D <level> as command-line option instead of just -D
* This aligns to clixon_cli and clixon_backend
* Application command option -S to clixon_netconf is obsolete. Use `clixon_netconf -l s` instead.
### Minor changes
* Added timeout option -t for clixon_netconf - quit after max time.
* Comply to RFC 8040 3.5.3.1 rule: api-identifier = [module-name ":"] identifier
* The "module-name" was a no-op before.
* This means that there was no difference between eg: GET /restconf/data/ietf-yang-library:modules-state and GET /restconf/data/XXXX:modules-state
