Result by keys (#754)

* Fix autodetection of dependencies when in a sub-repo.

* Some results improvements

- Added '--by-key' and '--by-key-compat' to 'pav results' this prints a subtable of results in a
  pretty way, and merges results across that subtable for multiple tests.
- Added optional arguments to expression functions. Wrap specs in the new Opt() class to use.
- Added high_pass_filter and low_pass_filter expression functions.

* Update base.py

* Update core.py

* Update base.py

* Style issues.

* Fixed unittest issues.
