Re: credential helper tests

Since we've had a few credential helpers posted to the list recently, I
really want to try them all out. This can be a little bit tricky for
automated testing, though, for two reasons:

  - they run on lots of platforms with lots of dependencies

  - they interact with parts of the systems that are opaque to git. So
    we can't make a test that reliably simulates "and then the user
    types 'foo' into a dialog box" across all platforms.

Instead, I came up with a separate test script that is intended to be
run interactively with the user. It runs the helpers through a battery
of tests, and tells the user what to expect and what to input to any
dialogs or prompts.

I've run it already on the helpers I've written. I plan on running it
with the helpers that have been posted, as well. But I also wanted to
make it public so that authors could use it as a development aid.

It's not integrated with git's tests at all. In theory it could be part
of t/, but disabled unless the user asks for it. However, I'm not sure
that makes much sense. It's intended to test helpers that aren't
necessarily even shipped with git, and wouldn't necessarily even need
git to run.

Perhaps throw it in somewhere under contrib/ hierarchy?
