test: Update trust git root
Marco Falke's old key expired, causing a travis error while verifying
commits 36afd4db44 and before:

    gpg: Good signature from "Marco Falke <marco.falke@tum.de>" [unknown]
    gpg:                 aka "Marco Falke <falke.marco@gmail.com>" [unknown]
    gpg: Note: This key has expired!
    Primary key fingerprint: B8B3 F1C0 E58C 15DB 6A81  D30C 3648 A882 F431 6B9B
      Subkey fingerprint: FE09 B823 E6D8 3A3B C798  3EAA 2D7F 2372 E50F E137

Update the trusted root commit to the commit after that, to fix
this issue.

Tooling for verification of PGP signed commits

This is an incomplete work in progress, but currently includes a pre-push hook script (pre-push-hook.sh) for maintainers to ensure that their own commits are PGP signed (nearly always merge commits), as well as a script to verify commits against a trusted keys list.

Using verify-commits.sh safely

Remember that you can't use an untrusted script to verify itself. This means that checking out code, then running verify-commits.sh against HEAD is not safe, because the version of verify-commits.sh that you just ran could be backdoored. Instead, you need to use a trusted version of verify-commits prior to checkout to make sure you're checking out only code signed by trusted keys:

git fetch origin && \
  ./contrib/verify-commits/verify-commits.sh origin/master && \
  git checkout origin/master

Note that the above isn't a good UI/UX yet, and needs significant improvements to make it more convenient and reduce the chance of errors; pull-reqs improving this process would be much appreciated.
