situations. Use them in most places where malloc, and friends are used.
This results in clean error messages in an out of memory situation instead of
segfaulting or silently malfunctioning. In some places, it just allows to
remove some logging code.

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.

which had lost their scoreboard slot during a prior graceful
restart, calls to ap_unregister_extra_mpm_process() were hidden
if AP_DEBUG (maintainer mode) wasn't defined.
This resulted in an uninitialized generation variable being
passed through to the child_status hook.

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.

mpm_winnt.c: MinGW doesn't currently define the Windows
STACK_SIZE_PARAM_IS_A_RESERVATION symbol
mpm_unix.c: Bypass all this code on Windows (too much trouble
to keep it out of Makefile)
mpm_common.h: Skip over definitions of functions not available on
Windows to keep references out of exports.c.

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
