Workaround for parallel_for() compilation issue with newer GNU compilers

Created new compute ADF for angular distribution function

apparently, data items used inside parallel_for() constructs have
rather strict requirements on const-ness, which is enforced by

copies of those class instances. This closes #1045

fix triclinic rounding bug for lib interface as well

Add src directory to PreventInSourceBuilds checks

added -restart2dump command-line option

cmake: prevent in-source build
