Some of it, most of it is due to switching from one fixed thread to the
potential of having lots more. The moving code around is mostly due to
other callers now having to use functions that were below them, and I'd
rather move them around instead of having prototypes at the top.

It would be easy to unify the two patches, but I wanted to separate the
switch from pdflush to 1 bdi thread from the transition from 1 bdi
thread to several.
