Fix shutdown/restart hangs in the threaded MPM.

After removing mod_cgid from my build (thanks, Jeff), I can do:
* apachectl graceful, followed by
* apachectl restart, followed by
* apachectl stop

...and get the results you would expect.

This is to fix a problem where the scoreboard is filled with
quiescing processes and no working processes can start, triggered by
MaxRequestsPerChild.  perform_idle_server_maintenance could theoretically
cause it as well.

determine how much data is returned to the previous filter.  Prior to this
change, we used a field in the conn_rec to determine how much to return.
After this change, we use an argument to ap_get_brigade.  This makes it
much more obvious how things work at all levels, so that module authors
can easily determine how much data is supposed to be returned to them.

modules to specify their own logging tags. mod_log_config
registers an optional function, ap_register_log_handler().
ap_register_log_handler() was being called by http_core before
the directive hash table was created. This patch creates the
directive hash table before ap_register_log_handler() is
registered as an optional function.

mod_log_config has registered an optional function, that other modules
can use to specify a function to be called.  This is analogous to the way
that mod_include works.  This also allows http to do the connection
logging itself, without exposing HTTP specific pieces to other modules.

request, then the byterange filter should not try to redo the
work.  The most common case of this happening, is a byterange
request going through the proxy, and the origin server handles
the byterange request.  The proxy should ignore it.

controversial change, because this is kind of HTTP specific.  However
many protocols should be able to take advantage of this kind of
information.  I expect that headers will need one more layer of
indirection for multi-protocol work, but this is a small step in
the right direction.
