  headers) for CGI. [Joe Orton, Rainer Jung]
- mod_reqtimeout: Fix a timed out connection going into the keep-alive
  state after a timeout when discarding a request body. Bug 51103.

- core: Do the hook sorting earlier so that the hooks are properly sorted
  for the pre_config hook and during parsing the config. [Stefan Fritsch]
