mention the changes to Apache for PR #6980

Changes with Apache 2.0.14-dev

  *) Fix a number of SGI compile warnings throughout the server.  Fix some

     bad parameters to apr_bucket_read().  Fix a bad statement in 

     ap_method_in_list().  For the mod_rewrite cache use apr_time_t 

     consistently; we were mixing apr_time_t and time_t in invalid ways 

     before.  In load_file(), call apr_dso_error() instead of 

     apr_strerror() so that we get a more specific string on some platforms.

  *) Allow modules to query the MPM about it's execution profile.  This

     query API can and should be extended in the future, but for now,

     max_daemons, and threading or forking is a very good start.
