Autocli optimization feature for generating smaller CLISPECs for large YANGs using treerefs
New `grouping-treeref` option added to clixon-autocli.yang Default is disabled, set to true to generate smaller memory footprint of clixon_cl Add prefix "mtpoint:" to cli api-paths to identify change of yang schemas

### Minor features
|
||||
|
||||
* Autocli optimization feature for generating smaller CLISPECs for large YANGs using treerefs
|
||||
* New `grouping-treeref` option added to clixon-autocli.yang
|
||||
* Default is disabled, set to true to generate smaller memory footprint of clixon_cli
|
||||
* Changed YANG uses/grouping to keep uses statement and flag it with YANG_FLAG_USES_EXP
|
||||
* Removed extras/ and build-root/ build code since they are not properly maintained
|
||||
* Refactored cli-syntax code to use cligen pt_head instead (long overdue)
