largefiles: link the core dirstate._changing context to the lfdirstate one

This will be much cleaner and safer to make sure the two dirstates are in sync.

This way, the large-files dirstate will simply inherit the state of the main
dirstate, so if the core code does the right thing, the large-files code should
be right too.

Set up repo

  $ hg --config experimental.treemanifest=True init repo
  $ cd repo

Requirements get set on init

  $ hg debugrequires | grep treemanifest
  treemanifest

Without directories, looks like any other repo

  $ echo 0 > a
  $ echo 0 > b
  $ hg ci -Aqm initial
  $ hg debugdata -m 0
  a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
  b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)

Submanifest is stored in separate revlog

  $ mkdir dir1
  $ echo 1 > dir1/a
  $ echo 1 > dir1/b
  $ echo 1 > e
  $ hg ci -Aqm 'add dir1'
  $ hg debugdata -m 1
  a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
  b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
  dir1\x008b3ffd73f901e83304c83d33132c8e774ceac44et (esc)
  e\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)
  $ hg debugdata --dir dir1 0
  a\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)
  b\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)

Can add nested directories

  $ mkdir dir1/dir1
  $ echo 2 > dir1/dir1/a
  $ echo 2 > dir1/dir1/b
  $ mkdir dir1/dir2
  $ echo 2 > dir1/dir2/a
  $ echo 2 > dir1/dir2/b
  $ hg ci -Aqm 'add dir1/dir1'
  $ hg files -r .
  a
  b
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b
  e

The manifest command works

  $ hg manifest
  a
  b
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b
  e

Revision is not created for unchanged directory

  $ mkdir dir2
  $ echo 3 > dir2/a
  $ hg add dir2
  adding dir2/a
  $ hg debugindex --dir dir1 > before
  $ hg ci -qm 'add dir2'
  $ hg debugindex --dir dir1 > after
  $ diff before after
  $ rm before after

Removing directory does not create an revlog entry

  $ hg rm dir1/dir1
  removing dir1/dir1/a
  removing dir1/dir1/b
  $ hg debugindex --dir dir1/dir1 > before
  $ hg ci -qm 'remove dir1/dir1'
  $ hg debugindex --dir dir1/dir1 > after
  $ diff before after
  $ rm before after

Check that hg files (calls treemanifest.walk()) works
without loading all directory revlogs

  $ hg co 'desc("add dir2")'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ mv .hg/store/meta/dir2 .hg/store/meta/dir2-backup
  $ hg files -r . dir1
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b

Check that status between revisions works (calls treemanifest.matches())
without loading all directory revlogs

  $ hg status --rev 'desc("add dir1")' --rev . dir1
  A dir1/dir1/a
  A dir1/dir1/b
  A dir1/dir2/a
  A dir1/dir2/b
  $ mv .hg/store/meta/dir2-backup .hg/store/meta/dir2

Merge creates 2-parent revision of directory revlog

  $ echo 5 > dir1/a
  $ hg ci -Aqm 'modify dir1/a'
  $ hg co '.^'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 6 > dir1/b
  $ hg ci -Aqm 'modify dir1/b'
  $ hg merge 'desc("modify dir1/a")'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m 'conflict-free merge involving dir1/'
  $ cat dir1/a
  5
  $ cat dir1/b
  6
  $ hg debugindex --dir dir1
     rev linkrev       nodeid    p1-nodeid    p2-nodeid

Merge keeping directory from parent 1 does not create revlog entry. (Note that
dir1's manifest does change, but only because dir1/a's filelog changes.)

  $ hg co 'desc("add dir2")'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 8 > dir2/a
  $ hg ci -m 'modify dir2/a'
  created new head

  $ hg debugindex --dir dir2 > before
  $ hg merge 'desc("modify dir1/a")'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg revert -r 'desc("modify dir2/a")' .
  reverting dir1/a
  $ hg ci -m 'merge, keeping parent 1'
  $ hg debugindex --dir dir2 > after
  $ diff before after
  $ rm before after

Create flat source repo for tests with mixed flat/tree manifests

  $ cd repo-flat

Status across flat/tree boundary should work

  $ hg status --rev '.^' --rev .

We can clone even with the knob turned off and we'll get a treemanifest repo.
