narrow_widen_acl: enforce narrowacl in narrow_widen (SEC)

Reviewer note: this was sent by the author as a simple bugfix, but can be
considered a security patch, since it allows users to access things outside
of the ACL, hence the (SEC) prefix.

However, this affects the `narrow` extention which is still marked as
experimental and has relatively few users aside from large companies with
their own security layers on top from what we can gather.
We feel (Alphare: or at least, I feel) like pinging the packaging list is
enough in this case.

actual stripping

  $ hg strip --config extensions.strip= --rev 'desc("c_dH0")'
  saved backup bundle to $TESTTMP/client/.hg/strip-backup/fe47ea669cea-a41bf5a9-backup.hg

Test that closing heads are ignored by default
-----------------------------------------------

  $ hg up 'desc("c_aG0")'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommit c_aJ0
  created new head

pushing the new head should fails

closing the head and pushing should succeed

------------------------------------------------------

  $ cat <<EOF >> $TESTTMP/single-head-server/.hg/hgrc

Because of previous test, we'll also push c_aL0 and c_aM0.

Let's make a new head and push everything. The server feedback will mention
exactly one new head because c_aM0 is closed.
