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.
