mod_dav improvement: make dav_method_propfind stream its response,
rather than cache every <response> object and send the whole 207 at once.
Note: this patch doesn't affect the mod_dav provider API at all.
Providers still return property results in text-buffers, but mod_dav
then streams them out immediately.

* mod_dav.h (dav_walker_ctx): add a brigade field and a scratchpool field.
* mod_dav.c (dav_send_one_response): new helper function to write a
<DAV:response> into a brigade/filter. this code has been factorized
out of dav_send_multistatus.
(dav_begin_multistatus): new factorized helper func; creates brigade
and sends initial <multistatus> tag.
(dav_send_multistatus): create brigade, call dav_begin_multistatus,
and switch all ap_rputs calls to ap_fputs instead. call
dav_send_one_response when looping over response list. use a
subpool when iterating.
(dav_method_propfind): initialize walker ctx's brigade. initialize
ctx's scratchpool as a subpool of r->pool. Send a <multistatus> tag
before calling the provider's walk() function, and a </multistatus>
tag afterwards.
(dav_stream_response): new function, originally based on
dav_add_repsonse. don't build linked list of responses in memory;
just spew each response object into the brigade via
dav_send_one_response(). take an incoming pool argument to do the
temporary allocation and streaming.
(dav_propfind_walker): pass ctx->scratchpool to dav_stream_response,
and clear the pool when finished.
