interfaces: introduce an interface for dirstate implementations

As usual with adding interface definitions, this describes the way
things are, not the way we'd like things to be. There are some clear
problems in the interface right now (eg ._map leaks in a few places),
but I have plans to clean those up. There are also many missing
docstrings, but again, we'll make a second pass to clean that up.

use the "debugbuildannotatecache" command to build annotate cache at rev 0

  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=0
  fastannotate: a: 1 new changesets in the main branch
  fastannotate: b: 1 new changesets in the main branch

"debugbuildannotatecache" should work with broken cache (and other files would
be built without being affected). note: linelog being broken is only noticed
when we try to append to it.

  $ echo 'CORRUPT!' >> .hg/fastannotate/default/a.m
  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=1
  fastannotate: a: rebuilding broken cache
  fastannotate: a: 2 new changesets in the main branch
  fastannotate: b: 1 new changesets in the main branch

  $ echo 'CANNOT REUSE!' > .hg/fastannotate/default/a.l
  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=2
  fastannotate: a: rebuilding broken cache
  fastannotate: a: 3 new changesets in the main branch
  fastannotate: b: 1 new changesets in the main branch

  $ rm .hg/fastannotate/default/a.m
  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=3
  fastannotate: a: rebuilding broken cache
  fastannotate: a: 4 new changesets in the main branch
  fastannotate: b: 1 new changesets in the main branch

  $ rm .hg/fastannotate/default/a.l
  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=3
  $ hg debugbuildannotatecache --debug --config fastannotate.mainbranch=4
  fastannotate: a: rebuilding broken cache
  fastannotate: a: 5 new changesets in the main branch
  fastannotate: b: 1 new changesets in the main branch

"fastannotate" should deal with file corruption as well

  $ rm -rf .hg/fastannotate
  $ hg fastannotate --debug -r 0 a
  fastannotate: a: 1 new changesets in the main branch
  0: 0

  $ echo 'CORRUPT!' >> .hg/fastannotate/default/a.m
  $ hg fastannotate --debug -r 0 a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 1 new changesets in the main branch
  0: 0

  $ echo 'CORRUPT!' > .hg/fastannotate/default/a.l
  $ hg fastannotate --debug -r 1 a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 2 new changesets in the main branch
  0: 0
  1: 1

  $ rm .hg/fastannotate/default/a.l
  $ hg fastannotate --debug -r 1 a
  fastannotate: a: using fast path (resolved fctx: True)
  fastannotate: a: cache broken and deleted
  fastannotate: a: 2 new changesets in the main branch
  0: 0
  1: 1

  $ rm .hg/fastannotate/default/a.m
  $ hg fastannotate --debug -r 2 a
  fastannotate: a: cache broken and deleted
  fastannotate: a: 3 new changesets in the main branch
