narrow: drop the bundle2 capability since we have server capabilities (BC)
This patch drops the narrow bundle2 capabilities since we introduced narrow
server capabilities which are more nice and now used everywhere.
I am not sure what it can affect, so on safe side I marked this as BC. Also I
removed the NARROWCAP constant as that kind of conflicts with the same name
constant in wireprototypes.py.

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

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
