Otherwise we'd only preload the ancestors that would fit the
page. That way, when a search result was on the first page, but the
ancestor didn't fit the page anymore. We would not have the preloaded
ancestor when rendering the hierarchy.

When a project is shared with a group, it should not be included as a
descendant on the group dashboard.

When searching we would limit the scope of ancestors to load because
the filter would be applied to the ancestors. Instead, we need to load
_all_ ancestors for matching projects.

Html code now works in commits atom feed `title` and `summary`.

Given no search term, the `search` and `search_with_secondary_emails` methods will yield an empty result set

Gitlab::Profiler.profile takes a URL to profile, and returns the ruby-prof
profile result.

This is currently only for interactive use (in a console) or from the script
runner. Note that when using this interactively, changes to the application
within that console session will be used, so this can be used to test proposed
performance changes.
