Fix the SSL filter logic. The SSL filter is not a network filter, because
it does not actually do the reading and writing to the network. By
moving that filter to in between CONNECTION and NETWORK filters, we ensure
that SSL is always called before the core.

Pull lingering close out of the pool cleanup phase. This was causing too
many bugs. Instead, it is called where it used to be called. I have
abstracted some of the logic out of the lingering close so that it gets

is in anticipation of a change to use a hook for the lingering close,

Get the proxy module compiling again. This is a hack to get past the
current compiler errors. Basically, the core now puts the socket
in the conn_rec->conn_config vector. The proxy grabs that socket and
uses it where it used to use the client_socket field from the conn_rec.
Long-term, all of the direct socket communication needs to be removed,
and this should go through a filter stack. Short-term, this gets the
proxy working again.
I have tested http and connect, but I haven't looked at the FTP proxy,
although it does compile now.

Allow modules that add sockets to the ap_listeners list to
define the function that should be used to accept on that
socket. Each MPM can define their own function to use for
the accept function with the MPM_ACCEPT_FUNC macro. This
also abstracts out all of the Unix accept error handling
logic, which has become out of synch across Unix MPMs.
The code flow is much easier now for different transports:
1) During pre-config, post-config or while parsing the config
file, add a socket to the ap_listeners list, making sure to
define an accept function at the same time.
2) MPMs find the correct listener, and call the accept function
that was defined in step 1.
3) That accept function returns a void pointer, which is passed
to the create_connection hook.
4) create_connection adds the correct low-level filters.

Remove commas from the end of the macros that define
directives that are used by MPMs. Previous to this patch,
you would use these macros without commans, which was unlike
any other directives. Now, after the macro, you must have

Begin to abstract out the underlying transport layer.
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.
