branchmap: avoid ancestor computations in absence of non-continous branches
The branchhead computation is one of the more heavy operations for
bigger repositories as it has to scan all changesets and potentially
involves the expensive computation of the ancestor sets. Redo the
computation to handle the common cases directly and use tighter
conditions for when the ancestor scan is necessary. Most importantly,
avoid it completely if the non-continous branches are processed in one
update as seen in the initial computation after a clone.
For the Mercurial repository, it gives a small 2-3% performance boost.
For the NetBSD test repository, it cuts the time in half.

persistent-nodemap: also list related file as part of the store
This make sure they are will be selected during upgrade, and copy based clone.

upgrade: explicitly test for revlog index
We do not want to exclude `.d` we want to only include `.i`. We are about to add
more extension type (for the persistent nodemap: `.n`, `.nd`) so lets make the
list explicit instead.

persistent-nodemap: highlight that node is not sent when streaming
We have a local work-around, however having that data sent in the first place
would be better. So we start with a test that monitor what is sent, and notice
they are not.

persistent-nodemap: test it (does not) exist after a stream clone
This is currently buggy. We add a test before fixing the bug.

persistent-nodemap: test that is it present after a clone
The persistent nodemap is actually missing after local and stream
clone. We start by adding a test for the case that works so that we
can compare output after the fix.

narrow: overwrite readfast in excludeddirmanifestctx
The excludeddirmanifestctx does not have underlying storage (because it is
excluded) so the implementation of the `readfast` trying to access it crash.
This was reveled while running some cache warning code on narrow repositories.
That code will be introduced further down in the series.
