Log Message:
Add cached_realpath()
realpath(3) is expensive, and meta mode at least uses it extensively.
We use cached_realpath() to save the result of successful calls to
realpath(3) in a private variable context.
This improves the worst case performance (eg examining libc with
nothing to do) by a factor of 4.
