copy{in,out}str: sync style with booke.
- early return in case of len == 0
- *done = 0 on fault

copy{in,out}str: Correctly return ENAMETOOLONG if source is not
NUL-terminated.

Use dcbst instead of dcbf to flush cache; the former does not invalidate
the cache line, which should be used immediately in most cases.

Cosmetic changes. No binary changes.
