Title: MAINT: optimize: clean up Zeros code

* Use standard C header file ``
* Decouple implementation from interface in `zeros.h` (expanded out the `ERROR` macro for readability)
* Don't use `static` variables, they make code non-reentrant and hinder compiler optimizations
* Indentation, `{}`, split multi-statement lines
