expectations of their usage.
The reason that we should make this change now is that we have changed
the implied meaning of AP_FTYPE_HTTP_HEADER - some users of this should
be PROTOCOL while others should be CONTENT_SET. In order to clarify it,
toss all of the bogus names and force the filter writers to make sure
they understand what they are doing.
CONTENT_SET is new (horrible name - change if you have better idea), but
it indicates that it should run between RESOURCE and PROTOCOL.
mod_deflate is the ideal CONTENT_SET filter.
The changed type names are:
CONTENT is now RESOURCE.
HTTP_HEADER is now PROTOCOL. However, most filters that used HTTP_HEADER
may want CONTENT_SET. (Only things like POP and HTTP belong as PROTOCOL.)
MMN bump since all filters need to be recompiled due to filter reordering.

phase. This moves us to inserting the filters in the create_request
phase. This makes more sense, because now the protocol filters are attached
to the request as soon as possible. Previously, some requests never
called the insert_filters phase, so they don't get the filters. Think
redirects for reqeusts that never call insert_filters.

was required to make sure that the sub request had the correct filters
when we went send the error page. With the new filter insertion logic,
this is no longer necessary.

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.

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.

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.

The content length filter seems to track bytes_sent properly regardless

- rename the create_connection hook to install_transport_filters
- move the point of invocation of the hook till after the call to
after ap_update_vhost_given_ip to enable the hook to use vhost

If you need the length, you should be using apr_brigade_length. This is
much more consistent. Of all the places that call ap_get_brigade, only
one (ap_http_filter) needs the length. This makes it now possible to
pass constants down without assigning them to a temporary variable first.
Also:
- Change proxy_ftp to use EXHAUSTIVE mode (didn't catch its -1 before)
- Fix buglet in mod_ssl that would cause it to return too much data in
some circumstances

separate from the input filter mode type.
We also no longer look at readbytes to determine the method of
filter operation. This makes the use of filters more obvious and
allows a wider range of options for input filters modes.
To start with, the new input filter modes are:
AP_MODE_READBYTES (no more than *readbytes returned)
AP_MODE_GETLINE (old *readbytes == 0 case)
AP_MODE_EATCRLF (old AP_MODE_PEEK)
AP_MODE_SPECULATIVE (will be used in a future ap_getline rewrite)
AP_MODE_EXHAUSTIVE (old *readbytes == -1 case)
AP_MODE_INIT (special case for NNTP over SSL)
The block parameter is an apr_read_type_e: APR_BLOCK_READ, APR_NONBLOCK_READ
This also allows cleanup of mod_ssl's handling in the getline case.

methods that mod_dav recognizes.
Note: this fixes a bug where a method (e.g. REPORT) would appear in a
Limit(Except) directive and Apache would register the method. The method
number in the request would then be something *other* than M_INVALID, which
threw off mod_dav's tests.

The first step is to remove the socket from the conn_rec,
the server now lives in a context that is passed to the
core's input and output filters. This forces us to be very
careful when adding calls that use the socket directly,
because the socket isn't available in most locations.

There were two len_read vars (each of different types), so the outer one
