* First version of clixon-autocli.yang semantics
* Default rules for module exclusion, list-keywords, completion, treeref-state
* Specialized rules for compress and exclusion of modules
* See [autocli documentation](https://clixon-docs.readthedocs.io/en/latest/cli.html#autocli)
* Obsoleted and moved autocli config options from clixon-config.yang to clixon-autocli.yang as follows:
* `CLICON_CLI_GENMODEL`, use: `autocli/module-default=false` instead
* Removed `clicon_cli_genmodel()`
* `CLICON_CLI_GENMODEL_TYPE`, use `autocli/list-keyword-default` and compress rules instead)
* Removed `clicon_cli_genmodel_type()`
* `CLICON_CLI_GENMODEL_COMPLETION`, use `autocli/completion-default` instead
* Removed `clicon_cli_genmodel_completion()`
* `CLICON_CLI_AUTOCLI_EXCLUDE`, use `autocli/rule/operation=exclude` instead
* `CLICON_CLI_MODEL_TREENAME`, use constant `AUTOCLI_TREENAME` instead
* Removed `clicon_cli_model_treename()`
* New YANG functions: yang_single_child_type, yang_find_namespace_by_prefix, yang_str2key
* Changed return values of yang_find_prefix_by_namespace
* Merged `cli_cli2xml()` into `cli2xml()`
* These were included for testing
* If you want to run the Clixon test suite you need to point `YANGMODELS`, see test/README.md
* The following configure options have been removed:
* `configure --with-opt-yang-installdir=DIR`
* `configure --enable-optyangs`
* You may need to specify standard YANGs using configure option `--with-yang-standard-dir=DIR`
* Updated yang ietf models with fetures for tet
* Added option `CLICON_YANG_AUGMENT_ACCEPT_BROKEN` to accept broken yangmodels.
* This is a debug option for CI testcases where standard YANG models are broken
* Added ancestor config cache indicating wether the node or an ancestor is config false or true
* Improved yang cardinality lookup
* Added yang_init(), called from all apps using yang
