  *) core/mod_http/mod_http2:
     - 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.
