* h2_from_h1 parses a HTTP/1.1 response into
* - response status
* - a list of header values
* - a series of bytes that represent the response body alone, without
* any meta data, such as inserted by chunked transfer encoding.
*
* All data is allocated from the stream memory pool.
*
* Again, see comments in h2_request: ideally we would take the headers
* and status from the httpd structures instead of parsing them here, but
* we need to have all handlers and filters involved in request/response
* processing, so this seems to be the way for now.
