into mod_mem_cache can cause it to overflow its cache buffer.

with anything that created a subreq.

(I don't think core_create_req is a good place for adding this filter.)

we would lose the extra filters.  Now, if a filter is added, it is run.
Unfortunately, this can cause an infinite loop, or it can cause request
headers to appear twice.  This commit removes two instances in the core
where we were inserting filters for a second and third time.  The bug
was that error responses were causing infinite loops.

This also removes the reset_filters function, which did the exact
same thing as add_required_filters.  The two functions were both called
in error conditions, which was part of what caused this bug.

must set the r->output_filter to r->proto_output_filter.  If we don't,
then as soon as we insert the request filter, the protocol filter will
be removed.  This was causing headers to not be sent on some requests.

this patch, the type wasn't too important, because all filters were
put on the same list.  After this patch, the filter type is very important,
because there are three different types of filters, and they are all treated
differently, namely:

CONNECTION:	Filters of this type are valid for the lifetime of this
		connection.
PROTOCOL:	Filters of this type are valid for the lifetime of this
		request from the point of view of the client, this means
		that the request is valid from the time that the request
		is sent until the time that the response is received.
CONTENT:	Filters of this type are valid for the time that this
		content is used to satisfy a request.  For simple requests,
		this is identical to PROTOCOL, but internal redirects
		and sub-requests can change the content without ending
		the request.

It is important to realize that the three major types above are actually
broken down into smaller groups in the code, to ensure that the ordering
of filters is always correct.

solution ensures that we don't lose filters if they are added later than
we expect.  The problem could be seen if a connection filter was added
after a request-based filter was added in the past.  The problem was that
the request-based filters pointed to the first filter in the connection
record, so the new connection filter was never called.  Now, all filters
are put on their correct filter lists, and we are sure to always update
all pointers when adding a filter.

were not getting the correct filters.  This is done by creating a location
in the request rec that holds protocol level filters.  Protocol level
filters survive for one request, from the time the request is received
from the user to the time the response is sent.  r->output_filters now
stores the request level filters, which are only valid for the lifetime
of one request_rec.

This patch works, but it is not complete.  The second half of the problem
is that add_any_filter doesn't check where it puts the filters that it
adds, so it is possible for filters to be put on this wrong list, and
for filters to be lost completely during request processing.  That half
of the fix will be coming in the next day or so.

allocate a wintty for prompting, which results in 4 prompts at
startup, 2 for each child and 2 within each when httpd "restarts

  next_filter of NULL to any ap_sub_req_lookup*() fn implies the subreq

  The comming fix will break invalid ap_sub_req_lookups* expecting to
  run subrequests with the next_filter NULL semantic.
