Set ap_max_mem_free at static initialization time so that the main thread,
created early from init_process(), has some (default) limits for its pool.

stopping a child process. The additional `graceful` parameter allows
registered hooks to free resources early during a graceful shutdown.

This is cleaner API than using pfds->pool implicitely.
MAJOR bump but reusing the existing hooks (with an API/ABI breakage) because
it's trunk material only.

It's now called automatically by mpm_event and anyway can't be called safely
outside the MPM code without racing.
MAJOR bump.

When a socket callback has a timeout, an associated timer event is used to
remove the sockets from the pollset and call a timeout function.
* This includes a noteworthy change to the main event loop. Previously,
we would call epoll, then process the timer events, then iterate through the
poll results. After this patch, the timer events are processed before the poll()
a _non-queued_ action can change the pollset conents (a users timed callback
function conversely could easily sit in a queue while the main thread continues
down into epoll)
* timer events can now have sockets associated with them, those sockets are
removed from the pollset when the timer event fires w/o a queue to the worker.
* timer events now have a canceled flag that can be toggled without locking
the timer list.
* Drop the severity of some wstunnel messages from DEBUG to TRACE1
* Lift the restriction on using asynchronous websockets connections but having
an idle timeout

when the thread/connection relationship changes. (Currently implemented
only for the Event MPM; should be implemented for all async MPMs.)

from the parsed (or default) config. This is useful for init scripts that
need to setup temporary directories and permissions, for example if those
temporary directories are located on a ram disk.

everywhere.
We know that the core module has module_index 0. Therefore we can save
some pointer operations in ap_get_module_config(cv, &core_module) and
ap_set_module_config(cv, &core_module, val). As these are called rather often,
this may actually have some (small) measurable effect.

processes. Add end_generation hook for notification when the last
MPM child of a generation exits.
end_generation is implemented completely by core using the
child_status hook run by the MPM.
simple and mpmt_os2 MPMs don't currently run the child_status
hook, so neither hook is invoked with those MPMs.

A new MPM can't be expected to manage the existing state,
particularly if that includes processes from the previous
generation.

ap_relieve_child_processes(): instead of requiring the MPM
to implement an otherwise-useless hook, just use a callback
function.
As I don't expect third-party MPM devs are following our day
to day progress, the API changes are considered part of
yesterday's MMN change.

ap_{reclaim,relieve}_child_processes; those functions can
invoke the hook directly; the function ap_mpm_note_child_killed()
is useless

related state has to be re-initialized to the default values
at pre-config time, but that was handled inconsistently by
the MPMs, resulting in unexpected behavior when some of the
directives were removed across restart
move that necessary initialization from the MPMs to common
code run from core's pre-config; MPMs that need to override
defaults can do so by running after core's pre-config (the
NetWare MPM now does that)
the DEFAULT_MAX_REQUESTS_PER_CHILD compile setting wasn't useful
enough to keep
the simple MPM wasn't consistent in which of these directives
were respected and which weren't, and that hasn't changed
(see procmgr.max_requests_per_child vs. ap_max_requests_per_child)

modules can and should be able to use this scoreboard information.
Rename suggestions for such a directive are welcomed.
Note that mod_status toggles the default, to present the ExtendedStatus
for server operators, whenever it is loaded. Docs changes to follow.
