This improves REPL usage consistency across ports, by utilizing the pyexec
code for the unix REPL.

Any '_' variables/functions in frozen modules are currently printed, when
they shouldn't be. That's due to underscore names possibly existing
between the start and end qstrs which are used to print the auto-complete
matches. The underscore names should be skipped when iterating between the
two boundary qstrs.
The underscore attributes are removed from the extra coverage exp file
because tab completing "import <tab>" no longer lists modules beginning
with an underscore.
