stringutil: refactor core of pprint so it emits chunks
This commit splits the core of pprint() to a new function that is
a generator of chunks instead of a function returning a single
value. This will make it possible to stream output without waiting for
all data to be formatted first. And it will make it easier to
implement support for indenting.
