* Fix cases with non blocking reads from the ap_http_filter input filter where

  chunk size lines or empty lines after a chunk are read incomplete. This can
  lead to a corruption inside the dechunking algorithm.
  This patch has an issue with larger chunk-extensions which need to get thrown
  away since we ignore them anyway.
