Update git submodules

* Update docs/submodules/odlparent from branch 'master'
  to 158af99fbc1a3aa904a3f92852d51eb5c3c7ecb9
  - Provide better traces with invalid URLs

    When a feature or bundle contains an invalid URL (or missing URL), the
    resulting plugin error is rather inscrutable. This attempts to improve
    the situation by indicating which feature is at fault.
