annotate: move annotatepair unit tests to a separate file

In upcoming patches the output is going to be significantly longer than it is
today, and doctests don't allow wrapping the output.

    data.

    Additionally, if `skipchild` is True, replace all other lines with parent
    annotate data as well such that child is never blamed for any lines.

    >>> oldfctx = b'old'
    >>> p1fctx, p2fctx, childfctx = b'p1', b'p2', b'c'
    >>> olddata = b'a\nb\n'
    >>> p1data = b'a\nb\nc\n'
    >>> p2data = b'a\nc\nd\n'
    >>> childdata = b'a\nb2\nc\nc2\nd\n'
    >>> diffopts = mdiff.diffopts()

    >>> def decorate(text, rev):
    ...     return ([(rev, i) for i in xrange(1, text.count(b'\n') + 1)], text)

    Basic usage:

    >>> oldann = decorate(olddata, oldfctx)
    >>> p1ann = decorate(p1data, p1fctx)
    >>> p1ann = _annotatepair([oldann], p1fctx, p1ann, False, diffopts)
    >>> p1ann[0]
    [('old', 1), ('old', 2), ('p1', 3)]
    >>> p2ann = decorate(p2data, p2fctx)
    >>> p2ann = _annotatepair([oldann], p2fctx, p2ann, False, diffopts)
    >>> p2ann[0]
    [('old', 1), ('p2', 2), ('p2', 3)]

    Test with multiple parents (note the difference caused by ordering):

    >>> childann = decorate(childdata, childfctx)
    >>> childann = _annotatepair([p1ann, p2ann], childfctx, childann, False,
    ...                          diffopts)
    >>> childann[0]
    [('old', 1), ('c', 2), ('p2', 2), ('c', 4), ('p2', 3)]

    >>> childann = decorate(childdata, childfctx)
    >>> childann = _annotatepair([p2ann, p1ann], childfctx, childann, False,
    ...                          diffopts)
    >>> childann[0]
    [('old', 1), ('c', 2), ('p1', 3), ('c', 4), ('p2', 3)]

    Test with skipchild (note the difference caused by ordering):

    >>> childann = decorate(childdata, childfctx)
    >>> childann = _annotatepair([p1ann, p2ann], childfctx, childann, True,
    ...                          diffopts)
    >>> childann[0]
    [('old', 1), ('old', 2), ('p2', 2), ('p2', 2), ('p2', 3)]

    >>> childann = decorate(childdata, childfctx)
    >>> childann = _annotatepair([p2ann, p1ann], childfctx, childann, True,
    ...                          diffopts)
    >>> childann[0]
    [('old', 1), ('old', 2), ('p1', 3), ('p1', 3), ('p2', 3)]
