previously built into Phil's test was clashing with the runtests.sh
framework. I think one of the core problems might be that scripts
which don't explicitly "exit 0" have return codes which vary depending
on the particular shell. (c.f. the autoconf portability guide.)
This might break the Debian test suite but I'm afraid I don't know
enough about how it works yet. Hopefully eventually it can become
just a wrapper around our 'make check'.
* make sure to build rsync before running 'make check'
* Put back in the loglevel concept from the samba scripts. If >8,
then turn on shell tracing.
* Allow tests to return 77 if they want to count as 'skipped'.
* Add more docs.
* Mangle Phil's script to get ready to run on non-Linux systems: we
need to not use shell functions, cp -a, etc. Not there yet.
