Merging patches

I'd prefer to have the 'relations' different from bundles. The way I see
this implemented:

* Add a table of (from_patch_id, to_patch_id, relation_type)
 * relation types would be something like:
   * "same-series" (identified by the x/n text)
   * "update" (either by looking at the patch 'proximity' or a v2 in
       the subject)
   * "addition" (not entirely sure how to detect this, maybe if the
       others don't match?)
* Add to the patch parser code to add suitable relations when possible
* Allow these relations to be (somehow) exposed in the patch list and/or
  patch page.

The last point is the hard bit, so I'd like any ideas you have on
exposing these relations. I was thinking of adding a "related patches"
list to the patch page (or a link to the set of related patches on a
separate page), grouped by relation type. This will let the maintainer
quickly grab all patches in one series (without needing to create a
bundle), or see that a patch has an update.

Cheers,
