- 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. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1899547 13f79535-47bb-0310-9956-ffa450edef68
