however backporting these doxygen fixes makes it significantly easier to diff
trunk and the 2.2.x branch, to sort out what's what. And we might as well
release with nicer doxygen markup.

Fixes and cleanups for mod_cache;

    * Add r->uri to the debug messages in the quick handler; makes debugging
      easier.
    
    * Always reset headers_in for lookup's, some modules make subrequests
      and then rewrite the url. Having a conditional request at this point
      is not what they expect (nor reasonable for them to handle). 

    * Don't store a per-request config on lookups; for the same reason.

    * Return DECLINED when in lookup mode and ap_meets_conditions() indicated
      we have the content but don't know if it's fresh or not. We have no idea
      whether the backend will have a 404, a 304 or any other kind of a 
      response - so we have to assume we cannot handle the request.

    * remove the unused "url" argument from the cache_create_entity() function

    * Whitespace/comment fixups in mod_cache.h

renegotiation is needed, and the request has a non-zero
content-length, or a t-e header (and 100-continue was not requested),
call ssl_io_buffer_fill to set aside the request body data if
possible, then proceed with the negotiation.
