dirstate: drop the now unused magic constants for the dirstate module

We no longer need them for the dirstate logic. We only need them in the
dirstate map (and parsers) logic.

This smell like progress.

Test rebase with obsolete
==========================

Enable obsolete

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log= {rev}:{node|short} {desc|firstline}{if(obsolete,' ({obsfate})')}
  > [experimental]
  > evolution.createmarkers=True
  > evolution.allowunstable=True
  > [phases]
  > publish=False
  > [extensions]
  > rebase=
  > drawdag=$TESTDIR/drawdag.py
  > strip=
  > EOF

Test that bookmark is moved and working dir is updated when all changesets have
equivalents in destination
  $ hg init rbsrepo && cd rbsrepo
  $ echo "[experimental]" > .hg/hgrc
  $ echo "evolution=true" >> .hg/hgrc
  $ echo root > root && hg ci -Am root
  adding root
  $ echo a > a && hg ci -Am a
  adding a
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo b > b && hg ci -Am b
  adding b
  created new head
  $ hg rebase -r 2 -d 1
  rebasing 2:1e9a3c00cbe9 tip "b"
  $ hg log -r .  # working dir is at rev 3 (successor of 2)
  3:be1832deae9a b (no-eol)
  $ hg book -r 2 mybook --hidden  # rev 2 has a bookmark on it now
  bookmarking hidden changeset 1e9a3c00cbe9
  (hidden revision '1e9a3c00cbe9' was rewritten as: be1832deae9a)
  $ hg up 2 && hg log -r .  # working dir is at rev 2 again
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  2:1e9a3c00cbe9 b (rewritten using rebase as 3:be1832deae9a) (no-eol)
  $ hg rebase -r 2 -d 3 --config experimental.evolution.track-operation=1
  note: not rebasing 2:1e9a3c00cbe9 mybook "b", already in destination as 3:be1832deae9a tip "b"
Check that working directory and bookmark was updated to rev 3 although rev 2
was skipped
  $ hg log -r .
  3:be1832deae9a b (no-eol)
  $ hg bookmarks
     mybook                    3:be1832deae9a
  $ hg debugobsolete --rev tip
  1e9a3c00cbe90d236ac05ef61efcc5e40b7412bc be1832deae9ac531caa7438b8dcf6055a122cd8e 0 (Thu Jan 01 00:00:00 1970 +0000) {'ef1': '4', 'operation': 'rebase', 'user': 'test'}

Obsoleted working parent and bookmark could be moved if an ancestor of working
parent gets moved:

  $ hg init $TESTTMP/ancestor-wd-move
  $ cd $TESTTMP/ancestor-wd-move
  $ hg debugdrawdag <<'EOS'
  >  E D1  # rebase: D1 -> D2
  >  | |
  >  | C
  > D2 |
  >  | B
  >  |/
  >  A
  > EOS
  $ hg update D1 -q
  $ hg bookmark book -i
  $ hg rebase -r B+D1 -d E
  rebasing 1:112478962961 B "B"
  note: not rebasing 5:15ecf15e0114 book D1 tip "D1", already in destination as 2:0807738e0be9 D2 "D2"
