* NACM extension (RFC8341)

Browse source 
* 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).
