[waffle] [PATCH v3 1/3] waffle utils: add wflinfo utility

[Chad Versace]

Jordan, thanks. The series looks good to me. I've pushed it, as well as
the Android patch, to master.

No one has yet verified that wflinfo doesn't break the Mac build, and
I didn't want to push code that was not build-tested. I also didn't want
to delay any longer on this series. So I slightly changed patch
1 (documented as v4 notes in the commit message) to prevent wflinfo from
building on Mac. I'll remove the Mac-guard this weekend, when I have
time to hack at home with my Mac. After that, I think waffle-1.4 should
be nearly ready.
