Snprintf2 (#1399) 
* Replaced many uses of sprintf with safer snprintf

Many very straightforward, but in a few cases added a length parameter to some private functions, because buffer length was otherwise unknowable.

* Removed unnecessary use of static on small buffers

This improves thread safety.

* Committing clang-format changes
