aac783bdf5 No longer depend on how fork() works when laying out segments... 
function pointers in shm are... nasty ;)

385da96d50 Use ap_state_query() to fix many modules that were not correctly initializing 
if they were not active during server startup but got enabled later during a
graceful restart (in which case they need to do all work during a single
config run).

84a5c9cd6f Remove the thread mutex from the worker... it really should be 
in the balancer. Thus we have global and thread for the balancer.
Use global when updating the full, shm list of workers; use
thread when being local.

55b9f8fba8 Here we go... we can now, via balancer-manager, add new 
workers to existing balancers. Still work to be done,
like error checking that we aren't trying to add more
than we can (right now, it fails, but it would be nice
to handle it nicer), disabling and *deleting* workers
we don't want anymore, the actual drain method, etc...
but this is some major goodness.

daa5a5c57c OK... a good commit point (we don't quite compile yet though...) 
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...

of the backend connection, instead of misusing the pool of the frontend
