chg: do not close dir fd while iterating

It works so long as the dp is the last entry, but readdir(dp) would fail
with EBADF. Let's not do that and close the dir fd explicitly.

===================================
Test repository filtering avoidance
===================================

This test file is a bit special as he does not check feature, but performance related internal code path.

Right now, filtering a repository comes with a cost that might be significant.
Until this get better, ther are various operation that try hard not to trigger
a filtering computation. This test file make sure we don't reintroduce code that trigger the filtering for these operation:

Setup
-----
  $ hg init test-repo
  $ cd test-repo
  $ echo "some line" > z
  $ echo a > a
  $ hg commit -Am a
  adding a
  adding z
  $ echo "in a" >> z
  $ echo b > b
  $ hg commit -Am b
  adding b
  $ echo "file" >> z
  $ echo c > c
  $ hg commit -Am c
  adding c
  $ hg rm a
  $ echo c1 > c
  $ hg add c
  c already tracked!
  $ echo d > d
  $ hg add d
  $ rm b

  $ cat << EOF >> $HGRCPATH
  > [devel]
  > debug.repo-filters = yes
  > [ui]
  > debug = yes
