* Added check for libxml in configure';
* Added clixon_util_regexp utility function
* Yang state get improvements
* Integrated state and config into same tree on retrieval, not separate trees
* Added cli functions `cli_show_config_state()` and `cli_show_auto_state()` for showing combined config and state info.
* Added integrated state in the main example: `interface/oper-state`.
* Added performance tests for getting state, see [test/test_perf_state.sh].
* Moved datastore/text/ code to datastore/ since there is only one type of datastore.
* Added "magic script line" to test script for sourced and scriped exits
* Added -p <dir> command-line option to all programs: backend, cli, netconf, restconf.
* Moved and updated all standard ietf and iana yang files from example and yang/ to `yang/standard`.
* Renamed example yang from example.yang -> clixon-example.yang
* Improved unknown handling
* Configure option `CLICON_YANG_DIR` is changed from a single directory to a path of directories
* Note CLIXON_DATADIR (=/usr/local/share/clixon) need to be in the list
://localhost/streams).
* Example: new stream "foo" will get access URL: https://localhost/streams/\
foo
* Optional pub/sub support enabled by ./configure --enable-publish
* Set publish URL base with: CLICON_STREAM_PUB_PREFIX (default http://local\
host/pub)
* Example: new stream "foo" will get pub URL: https://localhost/pub/foo
* These generated the Makefile variables: clixon_DBSPECDIR, clixon_SYSCONFDIR, clixon_LOCALSTATEDIR, clixon_LIBDIR, clixon_DATADIR which have been replaced by generic autoconf variables instead.
Instead of hardcode default config to /etc/clixon.xml, make it to
respect sysconfdir variable. Since autoconf doesn't expand variables on
header substitution it would end up being defined on clixon_config.h as
"${prefix}/etc/clixon.xml" what makes no sense for the header file.
Use eval to expand ${sysconfdir} and make .h file to be defined with
final directory name.
* Backend startup modes prior to 3.3.3. As enabled with `configure --with-startup-compat`. Configure option CLICON_USE_STARTUP_CONFIG is also obsoleted.
* Configuration files (non-XML) prior to 3.3.3. As enabled with `configure --with-config-compat`. The template clicon.conf.cpp files are also removed.
* Clixon XML C-lib prior to 3.4.0. As enabled with `configure --with-xml-compat`
