* move bzr-specific code from testsweet into bzrlib.selftest
* logging from within test suites is now done using python logging, so
the regular .bzr.log is not cluttered and the results can be easily
seen if the test fails
* don't capture stdout/stderr while running tests, instead let it leak
through so that we can see places where the library is doing its own
output and should be fixed.
