      mod_http2: new directive 'H2PushResource' to enable early pushes before 
     processing of the main request starts. Resources are announced to the 
     client in Link headers on a 103 early hint response. 
     All responses with status code <400 are inspected for Link header and
     trigger pushes accordingly. 304 still does prevent pushes.
     'H2PushResource' can mark resources as 'critical' which gives them higher
     priority than the main resource. This leads to preferred scheduling for
     processing and, when content is available, will send it first. 'critical'
     is also recognized on Link headers.
     
mod_proxy_http2: uris in Link headers are now mapped back to a suitable
     local url when available. Relative uris with an absolute path are mapped
     as well. This makes reverse proxy mapping available for resources
     announced in this header. 
     With 103 interim responses being forwarded to the main client connection,
     this effectively allows early pushing of resources by a reverse proxied
     backend server.
     adding support for newly proposed 103 status code.

      mod_dav: Fix a potential cause of unbounded memory usage or incorrect
behavior in a routine that sends <DAV:response>'s to the output filters.

The dav_send_one_response() function accepts the current head of the output
filter list as an argument, but the actual head can change between calls to
ap_pass_brigade().  This can happen with self-removing filters, e.g., with
the filter from mod_headers or mod_deflate.  Consequently, executing an
already removed filter can either cause unwanted memory usage or incorrect
behavior.

This patch changes the signature of the existing mod_dav's public API,
dav_send_one_response(), because this API is not yet a part of any 2.4.x
release.

* modules/dav/main/mod_dav.c
  (dav_send_one_response): Accept a request_rec instead of an ap_filter_t.
   Write the response to r->output_filters.
  (dav_send_multistatus, dav_stream_response): Update these calling sites
   of dav_send_one_response().

* modules/dav/main/mod_dav.h
  (dav_send_one_response): Adjust definition.
