util: add an interpolate() function to for replacing multiple values

util.interpolate can be used to replace multiple items in a string all at once
(and optionally apply a function to the replacement), without worrying about
recursing:

    >>> import util
    >>> s = '$foo, $spam'
    >>> util.interpolate(r'\$', { 'foo': 'bar', 'spam': 'eggs' }, s)
    'bar, eggs'
    >>> util.interpolate(r'\$', { 'foo': 'spam', 'spam': 'foo' }, s)
    'spam, foo'
    >>> util.interpolate(r'\$', { 'foo': 'spam', 'spam': 'foo' }, s, lambda s: s.upper())
    'SPAM, FOO'

The patch also changes filemerge.py to use this new function.
