Simplify and document/comment the handling of builtin import for:
- already-loaded modules
- built-in modules
- built-in umodules (formerly weak links)
- filesystem modules
Retains existing functionality with smaller code size but should also
facilitate potential new features (built-in packages, controlling the
frozen path).
Also makes the (unix-only) -m behavior a bit more obvious and configurable.
Code size change with this commit:
