filteredhash: split the computation of revision sets

The branch2's filteredhash combines the filtered revisions and the obsolete
ones, this will creates issue for implicit reference to heads we want to
introduce for the v3 of the branch cache format. So we isolate this logic for
alternative use.

#require rhg

  $ NO_FALLBACK="env RHG_ON_UNSUPPORTED=abort"

Rhg works well when sparse working copy is enabled.

  $ cd "$TESTTMP"
  $ hg init repo-sparse
  $ cd repo-sparse
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > sparse=
  > EOF

  $ echo a > show
  $ echo x > hide
  $ mkdir dir1 dir2
  $ echo x > dir1/x
  $ echo y > dir1/y
  $ echo z > dir2/z

  $ hg ci -Aqm 'initial'
  $ hg debugsparse --include 'show'
  $ ls -A
  .hg
  show

  $ tip=$(hg log -r . --template '{node}')
  $ $NO_FALLBACK rhg files -r "$tip"
  dir1/x
  dir1/y
  dir2/z
  hide
  show
  $ $NO_FALLBACK rhg files
  show

  $ $NO_FALLBACK rhg cat -r "$tip" hide
  x

  $ cd ..

We support most things when narrow is enabled, too, with a couple of caveats.

  $ . "$TESTDIR/narrow-library.sh"
  $ real_hg=$RHG_FALLBACK_EXECUTABLE

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > narrow=
  > EOF

A naive implementation of `rhg files` would leak the paths that are supposed
to be hidden by narrow.

  $ $NO_FALLBACK rhg files -r "$tip"
  dir1/x
  dir1/y
  $ "$real_hg" files -r "$tip"
  dir1/x
  dir1/y

The working copy version works with narrow correctly

  $ $NO_FALLBACK rhg files
  dir1/x
  dir1/y
  $ "$real_hg" files
  dir1/x
  dir1/y

Hg status needs to do some filtering based on narrow spec

  $ mkdir dir2
  $ touch dir2/q
  $ "$real_hg" status
  $ $NO_FALLBACK rhg --config rhg.status=true status

Adding "orphaned" index files:

  $ (cd ..; cp repo-sparse/.hg/store/data/hide.i repo-narrow/.hg/store/data/hide.i)
  $ (cd ..; mkdir repo-narrow/.hg/store/data/dir2; cp repo-sparse/.hg/store/data/dir2/z.i repo-narrow/.hg/store/data/dir2/z.i)
  $ "$real_hg" verify -q

  $ "$real_hg" files -r "$tip"
  dir1/x
  dir1/y

# TODO: even though [hg files] hides the orphaned dir2/z, [hg cat] still shows it.
# rhg has the same issue, but at least it's not specific to rhg.
# This is despite [hg verify] succeeding above.

  $ $NO_FALLBACK rhg cat -r "$tip" dir2/z
  z
  $ "$real_hg" cat -r "$tip" dir2/z
  z
