Log message:
- lots of clean up of 'const' usage.  Seems to have squished all
gcc warnings around const.  Mostly this involved adding lots of
missing const's.
- also add a few missing prototypes and header files.
- fix call to realpath (it was being given a pointer to a pointer rather
than a pointer).
