streamclone: new server config and some API changes for narrow stream clones

This patch introduces a new server config
`experimental.server.stream-narrow-clones` which if set to True will advertise
that the server supports narrow stream clones.

This patch also pass on the includes and excludes from getbundle command to
streamclone generation code.

There is a test added to show that the includepats and excludepats are correctly
passed.

Upcoming patches will implement storage layer filtering for streamclones and
then we can remove the temporary error and plug in the whole logic together to
make narrow stream clones working.

Tests narrow stream clones

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

Server setup

  $ hg init master
  $ cd master
  $ mkdir dir
  $ mkdir dir/src
  $ cd dir/src
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "f$x"; hg add "f$x"; hg commit -m "Commit src $x"; done

  $ cd ..
  $ mkdir tests
  $ cd tests
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "f$x"; hg add "f$x"; hg commit -m "Commit src $x"; done
  $ cd ../../..

Trying to stream clone when the server does not support it

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/f10" --stream
  streaming all changes
  remote: abort: server does not support narrow stream clones
  abort: pull failed on remote
  [255]

Enable stream clone on the server

  $ echo "[server]" >> master/.hg/hgrc
  $ echo "stream-narrow-clones=True" >> master/.hg/hgrc

Cloning a specific file when stream clone is supported

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/f10" --stream
  streaming all changes
  remote: abort: server does not support narrow stream clones
  abort: pull failed on remote
