the httpd core) is responsible for write completion.
Note that, with this commit, the Event MPM is still doing write
completion synchronously. I'll add async write completion as a
separate commit.
Note also that this commit breaks the (experimental) Leader/Followers
MPM on the (equally experimental) async-dev branch. The fix is to add
either synchronous or asynchronous write completion to that MPM. Rather
than hack in synchronous write completion, I'll revisit Leader/Followers
once I have async working in Event.

- A new End-Of-Request bucket is pushed through the output filter
chain after the last bucket of the response.
- This bucket gets destroyed by ap_core_output_filter() after the
buckets in front of it have been sent.
- The destroy callback of the EOR bucket invokes the access logger
and frees the request's pool.
With this change, the request logger now runs after the last byte of
the response is _sent_, rather than after the last byte of the response
is _generated_. This should make the bytes-sent count in the access
log more accurate in cases where the client closes the connection
midway through the sending of the response.

The big change is that it now does nonblocking writes when possible. The
goal of this redesign is to more cleanly support asynchronous write completion
in MPMs such as Event or Leader. However, the nonblocking writes may also
help in Worker and Prefork by allowing more overlapping of handler and
output filter processing with network writes.

a function I think, especially with the fact that
the mapping of getpid() to APR_PID_T_FMT isn't
consistant in some areas.

* This is useful for properly implementing a graceful stop and restart
where we want child processess to be able to carry on serving a request
but "de-listen" from a port. So that another instance entirely can be
started in our place, or to unbind from a "Listen" directive an admin
has removed from the configuration.

just before the final return. This gives modules an opportunity to do
something based on the proxy status.
A couple of examples where this is useful:
-You are using a caching module and would rather return stale content rather
than an error to the client if the origin is down.
-you proxy some subrequests (using SSI - mod_include) and do not want SSI
errors when the backend is down. If you would normally return
HTTP_BAD_GATEWAY, you may have a module that serves some other content.
new hook -- so mmn bump.. i made it a major one, hope thats ok

I will be adding documentation for the new directives hopefully in the next day or so.
* server/core.c: Added 'Protocol' to the core module config
Added ap_{set,get}_server_protocol API.
Added new directive: 'AcceptFilter'.
Enable 'httpready' by default on systems that support it. Use dataready filters for others.
* server/listen.c: Attempt to inherit protocols from Listener Records to Server configs.
The 'Listen' directive can now optionally take a protocol arg
Move bits that determined which accept filter is applied to core.c.
Added bits to find the correct accept filter based on the core's configuration.
* include/{ap_listen.h,http_core.h}: Add Protocol to respective structures.
* include/http_core.h: Add the accf_map table to the core_server_config structure
* include/ap_mmn.h: Minor MMN Bump for the new interfacces.
* modules/ssl/ssl_engine_init.c: Use the new protocol framework to enable mod_ssl for 'https' websites.

With Apache 1.3.x, it is a bit simpler as the request does
not go through ap_make_content_type().
Modules can set custom error responses but not be able to
set the charset, so they have to code the charset in the
html. Thus, it is useful to preserve 1.3.x behavior exactly.

generation in the scoreboard so that mod_status can accurately
represent workers in processes which are gracefully terminating.
New child processes with worker MPM can take over slots of
individual threads within gracefully terminating processes.
Sometimes this is a problem (too many of these gracefully
terminating processes), so it is helpful to have mod_status
provide the information required to recognize these processes.
