narrow: only walk files within narrowspec also for committed revisions

Narrow has been walking only paths matching the narrowspec when
walking the working copy. We have not done the same filtering when
walking committed revisions (e.g. "hg files -r "), which seems a
little odd. Let's make it consistent.

Differential Revision: https://phab.mercurial-scm.org/D4898

Test attempting a narrow clone against a server that doesn't support narrowhg.

  $ . "$TESTDIR/narrow-library.sh"

  $ hg init master
  $ cd master

  $ for x in `$TESTDIR/seq.py 10`; do
  >   echo $x > "f$x"
  >   hg add "f$x"
  >   hg commit -m "Add $x"
  > done

  $ hg serve -a localhost -p $HGPORT1 --config extensions.narrow=! -d \
  >    --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"
  $ hg serve -a localhost -p $HGPORT2 -d --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"

Verify that narrow is advertised in the bundle2 capabilities:

  $ cat >> unquote.py <<EOF
  > from __future__ import print_function
  > import sys
  > if sys.version[0] == '3':
  >     import urllib.parse as up
  >     unquote = up.unquote_plus
  > else:
  >     import urllib
  >     unquote = urllib.unquote_plus
  > print(unquote(list(sys.stdin)[1]))
  > EOF
  $ echo hello | hg -R . serve --stdio | \
  >   "$PYTHON" unquote.py | tr ' ' '\n' | grep narrow
  narrow=v0

  $ cd ..

  $ hg clone --narrow --include f1 http://localhost:$HGPORT1/ narrowclone

  abort: server does not support narrow clones

Make a narrow clone (via HGPORT2), then try to narrow and widen
into it (from HGPORT1) to prove that narrowing is fine and widening fails
gracefully:
  $ hg clone -r 0 --narrow --include f1 http://localhost:$HGPORT2/ narrowclone
