correction
no more references to apc_user_cache in apc_sma
better initialization of sma/cache 1st/3rd party
removal of some more locking from cache ( --APC_ATOM )
remove num_slots from apc.php, useless
cache_create_ex gone, cache_create takes sma
sma takes expunge and data reference
update apcue to work properly, add some testing insert/exists
