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

hg init
echo a > a
hg ci -Amadd       # 0

chmod +x a
hg ci -mexecutable # 1

hg up 0
rm a
ln -s symlink a
hg ci -msymlink    # 2
hg merge --debug

echo % symlink is local parent, executable is other

if [ -h a ]; then
    echo a is a symlink
    $TESTDIR/readlink.py a
elif [ -x a ]; then
    echo a is executable
else
    echo "a has no flags (default for conflicts)"
fi

hg update -C 1
hg merge --debug

echo % symlink is other parent, executable is local

if [ -h a ]; then
    echo a is a symlink
    $TESTDIR/readlink.py a
elif [ -x a ]; then
    echo a is executable
else
    echo "a has no flags (default for conflicts)"
fi
