Summary:
The eventual goal is to disable repoview filtering once narrow-heads is set.
The repoview layer is using a blacklist approach - scan through all heads (or
all drafts), and figure out what to blacklist. The new dag structure has a
larger constant factor on time complexity when it comes to many heads.
This diff disables repoview filtering entirely if 'narrow-heads' gets turned
on, as the first step moving to the whitelist approach. There are other isues,
which will be fixed in upcoming diffs.
