Ugh, this looks really hard.

dav_method_propfind has many call layers below it, and they *all*
assume that the provider is writing into a text-buffer. When control
returns to the top level, it sends out the whole buffer.

What we really want is for dav_method_propfind to look like
dav_method_report: create an output filter, pass it down to the
provider. The provider creates a brigade and spews data into it.
Voila, instant streaming.

But this looks like a total rewrite of dav_method_propfind to me. :-(
