This replaces the internal H2_HEADERS bucket, removing its
source file and also obsoletes any interim response parsing
needs.

filter to send responses through the output filter chain.
Specifically: the HTTP_HEADER output filter and ap_send_interim_response()
create a RESPONSE bucket and no longer are concerned with HTTP/1.x
serialization.
A new HTTP1_RESPONSE_OUT transcode filter writes the proper HTTP/1.x
bytes when dealing with a RESPONSE bucket. That filter installs itself
on the pre_read_request hook when the connection has protocol 'http/1.1'.

first request on this connection otherwise we assume we have just run
into a keepalive race and the backend is still healthy.

data bucket generators like ap_die might have changed the status
code. But we know better in this case and insist on the status
code that we have seen in the error bucket.

- adds new meta bucket types REQUEST, RESPONSE and HEADERS to the API.
- adds a new method for setting standard response headers Date and Server
- adds helper methods for formatting parts of HTTP/1.x, like headers and
end chunks for use in non-core parts of the server, e.g. mod_proxy
- splits the HTTP_IN filter into a "generic HTTP" and "specific HTTP/1.x"
filter. The latter one named HTTP1_BODY_IN.
- Uses HTTP1_BODY_IN only for requests with HTTP version <= 1.1
- Removes the chunked input simulation from mod_http2
- adds body_indeterminate flag to request_rec that indicates that a request
body may be present and needs to be read/discarded. This replaces logic
that thinks without Content-Length and Transfer-Encoding, no request
body can exist.

So it should not be in <var></var> in <syntax> and <code> should be used instead of <var> in explanations.
While at it, fix some other style issues and missing links spotted here and there.

create_secondary_connection and ap_create_secondary_connection()
to setup connections related to a "master" one, as used in
the HTTP/2 protocol implementation.
*) mod_http2: using the new API calls to get rid of knowledge
about how the core handles conn_rec specifics.
Improvements in pollset stream handling to use less sets.
Using atomic read/writes instead of volatiles now.
Keeping a reserve of "transit" pools and bucket_allocs for
use on secondary connections to avoid repeated setup/teardowns.

LimitXMLRequestBody can not exceed the size needed to ap_escape_html2() the
body without failing to allocate memory, so enforce this at load time based
on APR_SIZE_MAX, and make sure that ap_escape_html2() is within the bounds.
Document the limits for LimitXMLRequestBody in our docs.
