* Store all the local symbols in object files, not only the ones that need linker patches.
This generates better map/sym files, and thus allows for better debugging as well.
* Add comments explaining the ->src and the (void)arg;
* Mark `error` as a `format` function, to properly scan its format
* Fix the call to error() from parser.y:
- Use '%s' to avoid passing an arbitrary format
- Simplify yyerror overall
* Fix size parameter of %.*s format being an int... bonkers standard.
* Report the number of arguments required and provided on a STRFMT mismatch
* Add an assert to check for a very unlikely bug
While compiling for empscripten there is a duplicate symbol conflict with these two variables. And as they are only used locally, and do not need a symbol exported they can just be static.
