Issue1790: dirstate entry locked into unset if file mtime is set into
the future

Prepare test repo:

  $ hg init u
  $ cd u
  $ echo a > a
  $ hg add
  adding a
  $ hg ci -m1

Set mtime of a into the future:

  $ touch -t 203101011200 a

Status must not set a's entry to unset (issue1790):

  $ hg status
  $ hg debugstate
  n 644          2 2031-01-01 12:00:00 a

Test modulo storage/comparison of absurd dates:

#if no-aix
  $ touch -t 195001011200 a
  $ hg st
  $ hg debugstate
  n 644          2 2018-01-19 15:14:08 a

Verify that exceptions during a dirstate change leave the dirstate
coherent (issue4353)

valid.

Unused bytes counter is non-0 when appending

Transaction compatibility
-------------------------

The transaction preserves the dirstate.
We should make sure all of it (docket + data) is preserved

#if dirstate-v2
  $ hg commit -m 'bli'
#endif

  $ hg update --quiet
  $ hg revert --all --quiet
  $ rm -f a
  $ echo foo > foo
  $ hg add foo
  $ hg commit -m foo

#if dirstate-v2
  $ uid=$(find_dirstate_uuid)
  $ touch bar
  $ while [ uid = $(find_dirstate_uuid) ]; do
  >    hg add bar;
  >    hg remove bar;
  > done;
  $ rm bar
#endif
  $ hg rollback
  repository tip rolled back to revision 1 (undo commit)
  working directory now based on revision 1

  $ hg status

Check dirstate ordering
(e.g. `src/dirstate/` and `src/dirstate.rs` shouldn't cause issues)

  $ hg init repro
  $ cd repro
  $ mkdir src
  $ mkdir src/dirstate
  $ touch src/dirstate/file1 src/dirstate/file2 src/dirstate.rs
  $ touch file1 file2
  $ hg commit -Aqm1
  $ hg st
  $ cd ..
