Subject: pactest: add --review option

Opens the test file(s), test output, and any log files in the test
environment in an editor after the tests run for review.  Simplifies
debugging tests by avoiding the need to use --keep-root and manually
opening the relevant files.  The editor used can be set with --editor or
$EDITOR, falling back to vim.
