Previously we would log to ssh.log and sshd.log, but that is insufficient for tests that have more than one concurent ssh/sshd. Instead, we'll log to separate datestamped files in a $OBJ/log/ and leave a symlink at the previous location pointing at the most recent instance with an entry in regress.log showing which files were created at each point. This should be sufficient to reconstruct what happened even for tests that use multiple instances of each program. If the test fails, tar up all of the logs for later analysis. This will let us also capture the output from some of the other tools which was previously sent to /dev/null although most of those will be in future commits.
