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
