[PATCH 0/3] a few more leak fixes

[Jeff King <peff@peff.net>]

I was really bothered that using clang with SANITIZE=leak found a leak
that gcc didn't. And then I was doubly bothered to find that there is
one that gcc finds that clang doesn't!

I don't think either of these are urgent or important leaks on their
own, but the flaky nature of the results makes it annoying while trying
to find and clean up other leaks. So here are some fixes. Patches 1 and
3 are those two cases, respectively. Patch 2 is a more interesting
leak-fix enabled by the infrastructure added in patch 1.

  [1/3]: decorate: add clear_decoration() function
  [2/3]: revision: clear decoration structs during release_revisions()
  [3/3]: daemon: free listen_addr before returning
