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.

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.

Pull out the worker scoreboard cruft and start moving most
worker stuff to shm. Use slotmem for workers and provide
space for growth.
Redo logic:
ap_proxy_define_*
ap_proxy_create_*
ap_proxy_initialize_*
Right now just for workers, but lay framework for balancers
as well. The idea is to break out the functional parts
to make it easy for dynamics. Defining is simply describing
the worker, and tucking that info away. When we create, we
go ahead and create the shared memory, etc... Initialize
is simply to allow child process to access the shm...

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.

Reset the pointer to ap_logio_get_last_bytes each time we create or reinit an
existing scoreboard to avoid using an invalid pointer in case mod_logio got
reloaded to a different address.

Basicly the persistence is created by keeping the conn_rec structure
created for our backend connection (whether http or https) in the connection
pool. This required to adjust scoreboard.c in a way that its functions can
properly deal with a NULL scoreboard handle by ignoring the call or returning
an error code.

Solve one aspect, follow the _by_indexes() example for ap_get_scoreboard_worker

1. Rename worker_size, since this could easily be
confused with the actual MPM worker struct stuff.
2. Remove superflous ()s in the || test
3. Add superflous () in the pointer adjusting :)
Even though C prec rules make it clear what we
are doing, make it painfully obvious. Remove
