dirstate-v2: Add support when Rust is not enabled

This wires into `dirstatemap` the parser and serializer added in previous
changesets. The memory representation is still the same, with a flat `dict`
for `DirstateItem`s and another one for copy sources. Serialization always
creates a new dirstate-v2 data file and does not support (when Rust is not
enabled) appending to an existing one, since we don’t keep track of which
tree nodes are new or modified. Instead the tree is reconstructed during
serialization.

When a directory containing a tracked file gets symlinked, as of 5.8
`hg st` only gives the correct answer about clean (or deleted) files
if also listing unknowns.
The tree-based dirstate and status algorithm fix this:

#if symlink no-dirstate-v1

  $ cd ..
  $ hg init issue6335
  $ cd issue6335
  $ mkdir foo

  $ hg status
  ! foo/a
  ? bar/a
  ? foo

  $ hg status -c  # incorrect output with `dirstate-v1`
  $ hg status -cu
  ? bar/a
  ? foo
  $ hg status -d  # incorrect output with `dirstate-v1`
  ! foo/a
  $ hg status -du
  ! foo/a
  ? bar/a
  ? foo

  $ hg st -i -I 're:.*\.hs$'
  I A.hs
  I B.hs
  I ignored-folder/ctest.hs

#if dirstate-v2
