Initial void-safety changes. Current state of compilation is 107 errors, mostly VD88 (Configuration error: a class relies on another class with less strict void safety settings.)
Merge branch 'void-safety'

Conflicts:
	apps/adlc/app/adlc.ecf
	libraries/common_libs/src/utility/error_reporting/message_db.e
Small adjustments needed post-merge (not sure if merge is working completely properly - these changes were made and compiled in the void-safe branch...)
