* See also keywords generated by yacc/bison in clicon_yang_parse.tab.h, but they start with K_

* instead of Y_
|
|
* Wanted to unify these (K_ and Y_) but gave up for several reasons:
|
|
* - Dont want to expose a generated yacc file to the API
|
|
* - Cant use the symbols in this file because yacc needs token definitions
|
|
* - Use 0 as no keyword --> therefore start enumeration with 1.
