copies: move code into new manifestdict.filesnotin() method

copies._computeforwardmissing() finds files in one context that is not
in the other. Let's move this code into a new method on manifestdict,
so m1.filesnotin(m2) can be optimized for various types of manifests
(we expect more types of manifests soon).

def _computeforwardmissing(a, b):
    """Computes which files are in b but not a.
    This is its own function so extensions can easily wrap this call to see what
    files _forwardcopies is about to process.
    """
    missing = set(b.manifest().iterkeys())
    missing.difference_update(a.manifest().iterkeys())
    return missing

def _forwardcopies(a, b):
    '''find {dst@b: src@a} copy mapping where a is an ancestor of b'''

    # check for working copy
