run-tests: redefine --with-hg so it takes the 'hg' script to run.

- in parseargs(), check that --with-hg value is valid
- add handy --local option for "--with-hg=../hg"
- ensure that we always set PATH and PYTHONPATH (not just
  when doing a temporary install)
- override any existing PYTHONPATH, so test success does not
  depend on whatever happens to be in the caller's environment
- give tests a little more control by exporting $PYTHON to the
  environment; needed by test-convert and test-mergetool when
  they run hg with a stripped-down $PATH

Also, add a big comment explaining all the corner cases to test for the
next person who tries to modify this script.
