exchange: move simple narrow changegroup generation from extension

The narrow extension completely replaced the function generating the
changegroup part when a narrow changegroup was requested. Previous
commits have taught the in-core changegroup code how to filter files
based on a matcher. This commit teaches the in-core bundle2 part
generation code to construct a matcher based on arguments. It
will also emit a bundle2 part describing the narrow spec.

I believe the changegroup part generation code in the narrow extension
is now limited to ellipsis serving mode. i.e. core is now capable
of narrow changegroup generation when ellipsis mode is disabled.

#require unix-permissions

test that new files created in .hg inherit the permissions from .hg/store

  $ mkdir dir

just in case somebody has a strange $TMPDIR

  $ chmod g-s dir
  $ cd dir

  $ cat >printmodes.py <<EOF

  > import os
  > import sys

  >     for d in dirs:
  >         name = os.path.join(root, d)
  >         isdir[name] = 1
  >         allnames.append(name)
  >     for f in files:

  $ hg init repo
  $ cd repo

  $ chmod 0770 .hg/store

before commit
store can be written by the group, other files cannot
store is setgid

after commit
working dir files can only be written by the owner
files created in .hg can be written by the group
(in particular, store/**, dirstate, branch cache file, undo files)
new directories are setgid

Test that we don't lose the setgid bit when we call chmod.
Not all systems support setgid directories (e.g. HFS+), so
just check that directories have the same mode.

  $ cd ..
  $ hg init setgid
  $ cd setgid
  $ chmod g+rwx .hg/store
  $ chmod g+s .hg/store 2> /dev/null || true
  $ mkdir dir
  $ touch dir/file
  $ hg ci -qAm 'add dir/file'
  $ storemode=`$PYTHON ../mode.py .hg/store`
  $ dirmode=`$PYTHON ../mode.py .hg/store/data/dir`
  $ if [ "$storemode" != "$dirmode" ]; then
  >  echo "$storemode != $dirmode"
  > fi
  $ cd ..

  $ cd .. # g-s dir
