Use 'static' as much as possible

This change just inserts 'static' on runtime, tapset, and generated C
functions and globals, so the compiler can do a better job of
optimizing.

My tests with small scripts show ~10% reduction in compile time and ~20%
reduction in module size.  Larger scripts may show less benefit, but I
expect purely positive results.
