Merge r1769899 from trunk:

Added a note in the mod_headers docs about Content-Type and setifempty

This note has been added as a follow up of a stack overflow post
(thanks to Michael Allan for the research):

http://stackoverflow.com/questions/29398123/apache-2-4-set-mime-type-of-file-without-extension

After a chat in #httpd-dev it seems that the issue boils down to how %{CONTENT_TYPE}
is evaluated in util_expr_eval.c (r->content_type) vs how setifempty is (only a check
of the response headers). This particular behavior might be a bug or feature,
but it is worth to alert our users.

Merge of r1767936,1768160,1769192,1769550 from trunk:

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.

Merge r1688399 from trunk:

mod_remoteip: Use r->useragent_addr as the root trusted address for verifying.

This fixes issue resulting in setting of bad useragent_ip when internal
redirection has been generated as response to the request (typically as
result of "ErrorDocument 40x").

In this case, the original request has been handled by mod_remoteip and its
useragent_ip has been changed properly, but when internal redirection
to ErrorDocument has been generated later, the mod_remoteip's handler has been
executed again with *the same* c->client_addr as in the original request. If
c->client_addr IP is trusted, this results in bad useragent_ip being set.

When using r->useragent_addr as the root trusted address instead of
c->client_addr, the internal redirection uses the first non-trusted
IP in this particular case, so it won't change the r->useragent_ip during
the internal redirection to ErrorDocument.

Merge r1764040 from trunk:

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.

mod_proxy_fcgi: handle the HTTP 412 use case

This is a follow up of http://svn.apache.org/r1752347;
ap_meet_conditions could return a 412 status that if not
handled causes subsequent bogus reads and wrong messages
logged (like AH01070). After a chat on dev@ the feedback
was to couple HTTP_NOT_MODIFIED with HTTP_PRECONDITION_FAILED,
