RFR 8188226: jextract diagnostic generation should be improved

[Maurizio Cimadamore]

Looks good. Few questions:

* is the copyright date correct? Or should it be 2016, 2018 ?
* why the different code to access system properties e.g. 
Boolean.getBoolean (in Main) vs. PrivilegedAction (in LibClang) ?
