We don't need transfer_brigade() because we already have macros to do that

for us, and faster.  :)

Warning, though:  transfer_brigade() was equivalent to APR_BRIGADE_CONCAT(),
and I don't think that was the right behavior for one of the two callers!
I changed that one to use APR_BRIGADE_PREPEND() since by my inspection that
looks like what it should be, but please check me on this.
