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.

Clear rules when there are includes

  $ hg debugsparse --include *.py
  $ ls -A
  .hg
  data.py
  $ hg debugsparse --clear-rules
  $ ls -A
  .hg
  base.sparse
  data.py
  index.html
  readme.txt
  webpage.sparse

Clear rules when there are excludes

  $ hg debugsparse --exclude *.sparse
  $ ls -A
  .hg
  data.py
  index.html
  readme.txt
  $ hg debugsparse --clear-rules
  $ ls -A
  .hg
  base.sparse

Clearing rules should not alter profiles

  $ hg debugsparse --enable-profile webpage.sparse
