This package was already made obsolete 6 years ago (see commit
7d3b01db) and has not seen any significant updates since.

Cleanup cmake configuration and delete two unused job options.

D3PDs are no longer used in physics analysis and replaced by
derivations.

Do not put using declarations in the global namespace in headers.

Enable thread-safety checking.

 - Prefer pre-increment (or range-for) to postincrement.
 - Use unions rather than type punning.
 

Enable thread-safety checking.
Mark LArRoI_Map/LArRawOrdering as not thread-safe, as they use
old cabling tools + callbacks.
