arbitrary code before the handlers are invoked.

This resolves an issue with incorrect 304s on If-Modified-Since mod_include
requests since ap_meets_conditions() is not aware that this is a dynamic
request and it is not possible to satisfy 304 for these requests (unless
xbithack full is on, of course).  When mod_include runs as a filter, it is
too late to set any flag since the handler is responsible for calling
ap_meets_conditions(), which it should do before generating any data.

If a module doesn't need to run such arbitrary code, it can just pass NULL
as the argument and all is well.

  Previous to this commit, we would only process the buckets before the

AP_CONN_CLOSE
AP_CONN_KEEPALIVE

This also fixes a problem where ap_discard_request_body would not discard
the body when keepalive was 0.  This actually meant the keepalive status
was unknown *not* closed, but no one ever remembered that.

This problem was seen with mod_dav sending error responses (as reported by
Karl Fogel).

  Fixes Win32 cgi 500 errors when QUERY_ARGS or other strings include
  extended characters (non US-ASCII) in non-utf8 format.  This brings
  Win32 back into CGI/1.1 compliance, and leaves charset decoding up
  to the cgi application itself.

  Accomplished this by utf-8 encoding of plain octets for user and header
  data, so that the apr_proc_create() translates back to single unicode
  characters.  This won't necessarily translate into the correct octet
  depending on the codepage used by the cgi app.  That's the next task.
