Refactor deferral constants into corresponding headers.

Browse Source 
Currently there are deferral-relevant constants in arena.c and
background_thread.c. This commit moves them out into corresponding PAC
and HPA headers. Those commonly needed by both are put into a new header
deferral.h where the contract of deferral are clearly stated.
