This patch fixes various issues around chmod/chown/utimes:
- The chmod/chown/utimes approach uses open_async_internal, which only works
for files. This patch uses lookup_path so that chmod/chown is also
possible on directories.
- Implements SET_TO_SERVER for utimes
I never succeeded in getting all tests passing even without
these changes. Nor did I succeed in getting the CMake compilation to
work. Sorry. The patch includes extra unit tests for these calls.
We use the libary as part of a test harness to test an NFS server
implementation, so I am reasonably confident that the changes work.
They are also manually tested against the Linux Kernel NFS Server.
