bug#58985: 29.0.50; Have auth-source-pass behave more like other back ends

[J.P.]

Tags: patch

Hi people,

This is a belated follow-up to a brief exchange I had with Damien
earlier this year:

  https://lists.gnu.org/archive/html/bug-gnu-emacs/2022-04/msg00982.html

To recap, ERC would like to include the UNIX password store in the suite
of available back ends for its auth-source integration. To do that, we'd
need auth-source-pass to either export quite a few internal functions or
offer a bit more in the way of "standard" functionality. Thinking door
#2 the likelier, I've gone ahead and attempted a POC that mainly caters
to ERC's own requirements. (Sadly, I'm not well enough acquainted with
the library to aim much wider than that.) Regardless, I'm hoping someone
more knowledgeable will be willing to give this a think at some point.

Thanks,
J.P.
