dirstate-v2: Move fixed-size tree metadata into the docket file

Before this changeset, the dirstate-v2 data file contained not only nodes
and paths that may be reused when appending to an existing file,
but also some fixed-size metadata that applies to the entire tree
and was added at the end of the data file for every append.

This moves that metadata into the docket file, so that repeated "append"
operations without meaningful changes don’t actually need to grow any file.

Differential Revision: https://phab.mercurial-scm.org/D11098

Tests rebasing with part of the rebase set already in the
destination (issue5422)

Rebase two commits, of which one is already in the right place

  $ rebasewithdag -r C+D -d B <<EOF

Rebase with "holes". The commits after the hole should end up on the parent of
the hole (B below), not on top of the destination (A).
