Limit the threaded mpm to quiescing one process at a time.
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.

At the hack-athon we decided to change the way that input filters
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.
Revert about half of the last commit because of an oversight on my part
that broke it. Unfortunately, fixing the oversight "the right way" is
almost as ugly as the original code; it's easier to just go back to the way
it was, at least for now.
The problem is that the original code would delete buckets from foo through
bar in the brigade, and the patched code deletes *everything* up through
bar, which is bad. I could have fixed it by doing two splits, but that
introduces too many palloc's for my taste. It's also fixable with RING macros,
but I refuse to start using RING macros directly on brigades. The best
solution would be if there were a brigade equivalent to a RING_UNSPLICE/
RING_INSERT_HEAD sequence (this sequence is also used interally by
apr_brigade_split(), btw), something like this:
APR_BRIGADE_TRANSFER_BUCKETS(oldbrigade,newbrigade,startbucket,endbucket);
Absent that, the affected parts of the patch are hereby reverted (grumble,
grumble). If people liek the APR_BRIGADE_TRANSFER_BUCKETS() idea, I'll
implement that and repatch mod_include later.

Revert the change that moved keepalives out of conn_rec. That variable
controls the number of requests per connection, regardless of the protocol
used by the request.
Change mod_include to use the latest bucket API tricks. This gets
rid of some obscure while loop magic that had to be done before,
making mod_include easier to read and a better example for future
filter writers.
There should be no semantic changes in this patch... just a 1-to-1
mapping from while loops to bucket API calls that do the same thing.

Fix seg fault at start-up introduced by Ryan's change to enabl
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.

Allow modules to specify their own logging format specifier. Basically,
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.

There is a bug in how we sort some hooks, the pre-config hook is one that
is definately incorrect. Basically, the first time we call the pre-config
hooks, they are sorted correctly. However, when we call them the second
time, we use the order that modules are loaded into the server. This
move basically puts the http_module after mod_log_config in the compiled
server. It is a hack, and a work-around to allow for my next commit.
When the hook sort issue is solved, this should be re-named to config.m4

This changes the build process as outlined in my email earlier this week.
Essentially we now build the static objects, then allow a platform to run
a given command, build the shared modules, then run another command before exiting.
This gets us building dso's on beos and may provide a better framework for some of
the other "strange" platforms out there without stopping the normal ones working.

If a higher-level filter handles the the byterange aspects of a
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.

Add more options to the ap_mpm_query function. This also allows MPMs to

Convert the apr_create_signal_thread to apr_signal_thread. The main
difference, is that instead of creating a separate thread to listen for
signals, the thread that calls this function does the listening. Many
platforms have issues when the main thread isn't the thread that is
listening for signals. Even more platforms complain when the main thread
dies, but the process doesn't. This gets the main thread back to being
