Pieter-Jan Briers a6376368ee String safety (#1548) 
* Array size UB fixes

* Fix ShieldD

* Remove (almost) all unsafe strcpy calls

Bunch of macros. C arrays are easy enough and just need a different call. For various cases where a char* is passed around bare, I've made a TEXT_SPAN macro that can store a length too for bounds checking.

* Move crash handling in safe string operations to separate TU

* strcat safe version

* sprintf made safe too

* Fix compile
