bundle: don't send too many changesets (Issue1704)

The fast path in changegroupsubset can send too many csets. This happens
because it uses the parents of all bases as common nodes and then goes
forward from this again. If a base has a parent that has another child,
which is -not- a base, then this other child will nevertheless end up in
the changegroup.

The fix is to not use findmissing(), but use nodesbetween() instead, as
do the slow path and incoming/outgoing.

The change to test-notify.out is correct, because it actually hits this
bug, as can be seen by glog'ing the two repos:

@    22c88
|\
| o  0a184
| |
o |  0647d
|/
o  cb9a9

and

o  0647d
|
@  cb9a9

It used to pull 0647d again, which is unnecessary.

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path1 = /real/path1
# virtual/path2 = /real/path2
# virtual/root = /real/root/*
# / = /real/root2/*
# virtual/root2 = /real/root2/**
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# paths example: 
#
# * First two lines mount one repository into one virtual path, like
# '/real/path1' into 'virtual/path1'.
#
# * The third entry mounts every mercurial repository found in '/real/root'
# in 'virtual/root'. This format is preferred over the [collections] one,
# since using absolute paths as configuration keys is not supported on every
# platform (especially on Windows).
#
# * The fourth entry is a special case mounting all repositories in
# /'real/root2' in the root of the virtual directory.
#
# * The fifth entry recursively finds all repositories under the real root,
# and mounts them using their relative path (to given real root) under the
# virtual root.
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.
#
# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
