stringutil: add function to pretty print an object

This is inspired by the pprint() module/function (which we can't
use because the output is different on Python 2 and 3 - namely the
use of b'' literals).

We hook it up to `hg debugwireproto` for printing the response to
a wire protocol command.

This foreshadows future peer work, which will support decoding
CBOR responses into rich data structures.
