* 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()`
- 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
* Hello message semantics has been made stricter according to RFC 6241 Sec 8.1, for example:
* A client MUST send a <hello> element.
* Each peer MUST send at least the base NETCONF capability, "urn:ietf:params:netconf:base:1.1" (or 1.0 for RFC 4741)
* The netconf client will terminate (close the socket) if the client does not comply
* You can set `CLICON_NETCONF_HELLO_OPTIONAL` to true to use the old behavior of essentially ignoring hellos.
* New clixon-config@2020-03-08.yang revision
* Added: `CLICON_NETCONF_HELLO_OPTIONAL`
* The base capability has been changed to "urn:ietf:params:netconf:base:1.1" following RFC6241.
* Replaces the hardcoded "config" keyword.
* Implemented by a compile-time option called `DATASTORE_TOP_SYMBOL` option in clixon_custom.h
* Tests: added endtest to all tests. Removed all premature exits if BE=0
* Only requests on the form: `<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><edit-config>...` will be accepted
* All replies will be on the form: `<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">...`
* Requests such as: `<rpc><edit-config>...` will not be accepted.
* You can revert this behaviour (to clixon pre-4.6 behaviour) by enabling `CLICON_NAMESPACE_NETCONF_DEFAULT`
* This API change is a consequence of: [copy-config's RPC cxobj parameter does not contain namespace #131](https://github.com/clicon/clixon/issues/131)
