rrsync improvements

- Convert rrsync to python.
- Enhance security of arg & option checking.
- Reject `-L` (`--copy-links`) by default.
- Add `-munge` and `-no-del` options.
- Tweak the logfile line format.
- Created an rrsync man page.
- Use `configure --with-rrsync` if you want `make install` to install
  rrsync and its man page.
- Give lsh more rrsync testing support.
