Changes with Apache 2.4.10

  *) mod_reqtimeout: Resolve unexpected timeouts on keepalive requests 
     under the Event MPM. PR56216.  [Frank Meier <frank meier ergon ch>]

     "http-equiv" meta tag. PR 56287 [Micha Lenk <micha lenk info>]

  *) Add suspend_connection and resume_connection hooks to notify modules
     when the thread/connection relationship changes.  (Should be implemented
     for any third-party async MPMs.)  [Jeff Trawick]

     in order to utilize the request record from within these tables.

  *) mod_lua: Add a fixups hook that checks if the original request is intended 
     for LuaMapHandler. This fixes a bug where FallbackResource invalidates the 
     LuaMapHandler directive in certain cases by changing the URI before the map 
     handler code executes [Daniel Gruno, Daniel Ferradal <dferradal gmail com>].
