    If a subreq added a filter (say INCLUDES) and the subreq was promoted via · 07060a28

    fast_redirect, the filter would still point at the subreq - rather than
    the original r.  So, we must update any filters pointing at rr to be r.
    
    This would cause lots of problems with mod_include with mod_dir requests
    such as seen in PR 7966.  mod_include would be unsetting the headers_out
    of rr instead of r.  But, we disassociate rr->headers_out and r->headers_out.
    Therefore, the C-L header in r->headers_out would remain - even though it
    bears no relation to what we will be outputting - causing problems.
    
    This also now permits chunked-encoding of mod_dir/mod_include requests
    which could never happen before and fixes the content-length problem
    seen in PR 7966.
    
    As hinted at in PR 7966, there is a race condition - if for some reason
    the server stalls reading an included file (or even better, placing a
    sleep in the cgi-bin script!), the invalid C-L may get propogated to the
    client.
    
    (Note that internal_internal_redirect has this same code fragment.)
