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.

#!/bin/sh

# In the merge below, the file "foo" has the same contents in both
# parents, but if we look at the file-level history, we'll notice that
# the version in p1 is an ancestor of the version in p2.  This test
# makes sure that we'll use the version from p2 in the manifest of the
# merge revision.

hg init repo
cd repo

echo foo > foo
hg ci -qAm 'add foo'

echo bar >> foo
hg ci -m 'change foo'

hg backout -r tip -m 'backout changed foo'

hg up -C 0
touch bar
hg ci -qAm 'add bar'

hg merge --debug
hg debugstate | grep foo
hg st -A foo
hg ci -m 'merge'

hg manifest --debug | grep foo
hg debugindex .hg/store/data/foo.i
