Remove the MPM_SYNC_CHILD_TABLE macro since there is no longer a scoreboard
file that needs to be synched.

Add an allocator-passing mechanism throughout the bucket brigades API.
From Apache's standpoint, the apr_bucket_alloc_t* used throughout a given
connection is stored in the conn_rec by the create_connection hook. That
means it's the MPM's job to optimize recycling of apr_bucket_alloc_t's --
the MPM must ensure that no two threads can ever use the same one at the
same time, for instance.

mode to not "daemonize" while detaching from the controlling terminal.
This is necessary for Apache to work with process-management tools like
AIX's "System Resource Controller" as well as Dan Bernstein's "daemontools".
What this means is apache must _NOT_ be a process group leader if called
with the -DNO_DETACH flag.

create the scoreboard's shared memory segment. We now have the best of
both worlds:
if config specifies ScoreBoardFile
create name-based shared memory, errors are fatal
else /* we get to choose */
create anonymous shared memory
if ENOTIMPL
create name-based shared memory from DEFAULT_SCOREBOARD
else
errors are fatal
This gives us the flexibility to have anonymous shared memory (on platforms
that support it) as well as name-based shared memory when third-party
programs want access to our scoreboard.
The ap_scoreboard_fname static variable is now owned by the scoreboard.c
file, and no longer by the MPMs. The MPMs MUST NOT set ap_scoreboard_fname
to a default, since that will override the default creation logic and
only allow name-based segments.

- move the point of invocation of the hook till after the call to

vhost becomes the 'vhost name string' so it now survives ap_generation
clicks. next was apparently never used.
This patch also accounts for the changes to the apr_shm api, and gives
Win32 the magic of a shared scoreboard.
Breakage aplenty on non-win32 platforms, I suspect, but this radical
surgery, and culling of unused functions, was really, really needed.

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
the socket from the connection using the core's conn_config vector. This
is in anticipation of a change to use a hook for the lingering close,
which I hope to do soon.

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
a comma. This makes the macros look more like the rest of the
directives.
I know this is cosmetic, and I was going to leave it alone, but when
I found out that it bothered Cliff too, I decided to fix it after all.

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.

a cleanup registered with the connection_pool. I have also turned
ap_lingering_close into a static function, because it is only used
in connection.c. This is the next step to consolidating all of the
socket function calls. ap_lingering_close will only be added if the
core is dealing with a standard socket.

**WARNING** This will of course break the compile on any third-party MPMs
you might have floating around, but it's a really quick change to make.

support it. This defines a symbol called AP_SIG_GRACEFUL in
ap_config_auto.h which will have the appropriate signal value. All
direct references to SIGWINCH have been replaced with AP_SIG_GRACEFUL.
On Linux 2.0, use SIGWINCH instead since SIGUSR1 is used by glibc
2.0's user-space threading library to control threads. All later
versions of Linux/glibc don't have this problem. (Not to mention the
security holes in older Linux versions which make it unsuitable for
use as a web server.) If your platform doesn't have SIGUSR1, use the
appropriate mojo in configure to define what your graceful restart
signal should be.
In theory, a configure switch could be added to allow the admin to
specify the appropriate signal that should be used. This is left
as an exercise to the reader for now.
The docs need to be updated. Since the signal is now configurable,
just saying SIGUSR1 for graceful restart isn't completely true. Also,
the apachectl functionality needs to be moved into httpd - this is
what Win32 does and it makes us consistent across platforms.
Roy issued a veto against use of SIGWINCH by default, so this should
resolve that veto.

MPMs use the same functions for all common MPM directives. This
should make it easier to catch all bugs in these directives once.
Everybody should check their favorite MPM to ensure that it still
compiles, and that these directives work. This is a big patch, and
although it looks good, and things compiled for me, that is no
garauntee that it will work on all platforms. :-)

We tried to make all of the MPMs report their threading capabilities

It's not perfect, but it's a long way towards it. The problem turned out
to be simple, we weren't resetting the poll selections before we went into
poll for the second time. Not sure if this means our poll impl. using
select is broken or not?
It also changes us to use the new UDP in APR. With these changes and some
