More XPath function support

* `count`, `name`, `contains`, `not`, as defined in [xpath 1.0](https://www.w3.org/TR/xpath-10)
  * `deref`, `derived-from` and `derived-from-or-self` from RFC7950 Section 10.
    * in particular in augment/when statements
  * Improved error handling
    * Verification of XPath functions is done at startup when yang modules are loaded, not when XPaths are evaluated.
    * Separation of "not found" and "not implemented" XPath functions
    * Both give a fatal error (backend does not start).
