store: lazily get file size on demand for the fncache case

We don't have the information in the first place, so we can avoid querying the
file system inconditionnaly for use case we don't needs it.

This change requires the StoreFile class to be passed a vfs to retrieve the
file_size if needed.

In the non-fncache case, we already have the information from file system
walking, so we keep it and use it.

#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

  $ hg clone --narrow  ./repo-sparse repo-narrow --include dir1

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
