Enforce proper memory ordering in refcnt_rele() and refcnt_finalize() Make refcnt_rele() and refcnt_finalize() order memory operations so that preceding loads and stores happen before 1->0 transition. Also ensure that loads and stores that depend on the transition really begin only after the transition has occurred. Otherwise the object destructor might not see the object's latest state. OK bluhm@

Add refcnt_shared() and refcnt_read() refcnt_shared() checks whether the object has multiple references. When refcnt_shared() returns zero, the caller is the only reference holder. refcnt_read() returns a snapshot of the counter value. refcnt_shared() suggested by dlg@. OK dlg@ mvs@

introduce a wrapper around reference counts called refcnt. its basically atomic inc/dec, but it includes magical sleep code in refcnt_finalise that is better written once than many times. refcnt_finalise sleeps until all references are released and does so with sleep_setup and sleep_finalize, which is fairly subtle. putting this in now so i we can get on with work in the stack, a proper discussion about visibility and how available intrinsics should be in the kernel can happen after next week. with help from guenther@ ok guenther@ deraadt@ mpi@
