52d6325133 New pool method poolsegpoolgen gets the pool generation for a segment. (this allows the segment whiten and reclaim methods not to need to know the pool class.)

2a24ad79df Since we know that a segment belongs to a pool with a format at the point where we call segwalk, it makes sense to pass the format.

79d301f528 Cherry-pick change 192595 from custom/cet/main, removing mps_addr_object. this function failed to solve the problem of decoding the stack on 64-bit windows, because the stack may need to be decoded after an mps assertion failure, in which case the arena lock is held and mps_addr_object cannot be called. we eventually solved the problem in a different way (using mps_arena_postmortem) and mps_addr_object is no longer used.

5c31ca3cab Rename the "protection mutator context" module to "mutator context" (this module handles mutator context decoding for both the protection module and the thread module). 
Rename functions Prot{Can,}StepInstruction to MutatorContext{Can,}StepInstruction so that they follow the naming convention in guide.implc.naming.prefix.program.
Move mutator context declarations out of prot.h into new header prmc.h.
Correct .assume.null in a couple of places -- it's not safe for MutatorContextStepInstruction to return ResUNIMPL, instead MutatorContextCanStepInstruction should return FALSE.

8340e390a5 In order to be able to test mps_arena_busy in all build configurations, we must always take and release the arena lock, even in the single-threaded case. we gain some additional checking by doing this, at low cost (since in this build configuration the locks are generic and so just increment/decrement a count of claims). 
In the CONFIG_POLL_NONE we configuration, we would still like to check that no traces are busy when leaving the arena, but since we now call ArenaLeave in this configurations, move the assertion to ShieldLeave.
In ArenaDestroy, call ArenaLeave, don't just release the lock.
