* NACM extension (RFC8341)

* NACM module support (RFC8341 A1+A2)
   * Recovery user "_nacm_recovery" added.
     * Example use is restconf PUT when NACM edit-config is permitted, then automatic commit and discard are permitted using recovery user.
   * Example user changed adm1 to andy to comply with RFC8341 example

 * Yang code upgrade (RFC7950)
   * RPC method input parameters validated
     * see https://github.com/clicon/clixon/issues/4
* Correct XML namespace handling
   * XML multiple modules was based on "loose" semantics so that yang modules were found by iterating thorugh namespaces until a match was made. This did not adhere to proper [XML namespace handling](https://www.w3.org/TR/2009/REC-xml-names-20091208), and causes problems with overlapping names and false positives. Below see XML accepted (but wrong), and correct namespace declaration:
```
      <rpc><my-own-method></rpc> # Wrong but accepted
      <rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> # Correct
        <my-own-method xmlns="http://example.net/me/my-own/1.0">
      </rpc>
```
   * To keep old loose semantics set config option CLICON_XML_NS_ITERATE (true by default)
   * XML to JSON translator support for mapping xmlns attribute to module name prefix.
   * Default namespace is still "urn:ietf:params:xml:ns:netconf:base:1.0"
   * See https://github.com/clicon/clixon/issues/49
* Changed all make tags --> make TAGS
* Keyvalue datastore removed (it has been disabled since 3.3.3)
* debug rpc added in example application (should be in clixon-config).

### Major New features
* NACM extension (RFC8341)
* Move NACM files from backend to lib src dir
* NACM module support (RFC8341 A1+A2)
* Recovery user "_nacm_recovery" added.
* Example use is restconf PUT when NACM edit-config is permitted, then automatic commit and discard are permitted using recovery user.
* Example user changed adm1 to andy to comply with RFC8341 example
* Yang code upgrade (RFC7950)
* YANG parser cardinality checked (https://github.com/clicon/clixon/issues/48)
* See https://github.com/clicon/clixon/issues/84
* RPC method input parameters validated
* see https://github.com/clicon/clixon/issues/47
* Support of submodule, include and belongs-to.
* Openconfig yang specs parsed: https://github.com/openconfig/public
* Improved unknown handling
* Improved "unknown" handling
* Yang load file configure options changed
* `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
* CLICON_YANG_MAIN_FILE Provides a filename with a single module filename.
* CLICON_YANG_MAIN_DIR Provides a directory where all yang modules should be loaded.
* Correct XML namespace handling
* XML multiple modules was based on "loose" semantics so that yang modules were found by iterating thorugh namespaces until a match was made. This did not adhere to proper [XML namespace handling](https://www.w3.org/TR/2009/REC-xml-names-20091208), and causes problems with overlapping names and false positives. Below see XML accepted (but wrong), and correct namespace declaration:
```
<rpc><my-own-method></rpc> # Wrong but accepted
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> # Correct
<my-own-method xmlns="http://example.net/me/my-own/1.0">
</rpc>
```
* To keep old loose semantics set config option CLICON_XML_NS_ITERATE (true by default)
* XML to JSON translator support for mapping xmlns attribute to module name prefix.
* Default namespace is still "urn:ietf:params:xml:ns:netconf:base:1.0"
* See https://github.com/clicon/clixon/issues/49
### API changes on existing features (you may need to change your code)
* Yang parser is stricter (see above) which may break parsing of existing yang specs.
* XML namespace handling is corrected (see above)
* For backward compatibility set config option CLICON_XML_NS_ITERATE
* Yang parser functions have changed signatures. Please check the source if you call these functions.
* Add `<CLICON_YANG_DIR>/usr/local/share/clixon</CLICON_YANG_DIR>` to your configuration file, or corresponding CLICON_DATADIR directory for Clixon system yang files.
* Change all @datamodel:tree to @datamodel in all CLI specification files

* For backward compatibility, define CLICON_CLI_MODEL_TREENAME_PATCH in clixon_custom.h
### Minor changes
* Changed all make tags --> make TAGS
* Keyvalue datastore removed (it has been disabled since 3.3.3)
* Removed return value ymodp from yang parse functions (eg yang_parse()).
* New config option: CLICON_CLI_MODEL_TREENAME defining name of generated syntax tree if CLIXON_CLI_GENMODEL is set.
* XML parser conformance to W3 spec

* getopt return value changed from char to int (https://github.com/clicon/clixon/issues/58)
### Known issues
* debug rpc added in example application (should be in clixon-config).
