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.

test sparse with --verbose and -T json

  $ hg init myrepo
  $ cd myrepo
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > sparse=
  > strip=
  > EOF

  $ echo a > show
  $ echo x > hide
  $ hg ci -Aqm 'initial'

  $ echo b > show
  $ echo y > hide
  $ echo aa > show2
  $ echo xx > hide2
  $ hg ci -Aqm 'two'

Verify basic --include and --reset

  $ hg up -q 0
  $ hg debugsparse --include 'hide' -Tjson
  [
   {
    "exclude_rules_added": 0,
    "files_added": 0,
    "files_conflicting": 0,
    "files_dropped": 1,
    "include_rules_added": 1,
    "profiles_added": 0
   }
  ]
  $ hg debugsparse --clear-rules
  $ hg debugsparse --include 'hide' --verbose
  removing show
  Profiles changed: 0
  Include rules changed: 1
  Exclude rules changed: 0

  $ hg debugsparse --reset -Tjson
  [
   {
    "exclude_rules_added": 0,
    "files_added": 1,
    "files_conflicting": 0,
    "files_dropped": 0,
    "include_rules_added": -1,
    "profiles_added": 0
   }
  ]
  $ hg debugsparse --include 'hide'
  $ hg debugsparse --reset --verbose
  getting show
  Profiles changed: 0
  Include rules changed: -1
  Exclude rules changed: 0

Verifying that problematic files still allow us to see the deltas when forcing:

  $ hg debugsparse --include 'show*'
  $ touch hide
  $ hg debugsparse --delete 'show*' --force -Tjson
  pending changes to 'hide'
  [
   {
    "exclude_rules_added": 0,
    "files_added": 0,
    "files_conflicting": 1,
    "files_dropped": 0,
    "include_rules_added": -1,
    "profiles_added": 0
   }
  ]
  $ hg debugsparse --include 'show*' --force
  pending changes to 'hide'
  $ hg debugsparse --delete 'show*' --force --verbose
  pending changes to 'hide'
