b4a3d0824b 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.

437bf9c6a4 Rename mutatorfaultcontext to mutatorcontext because this data structure is not only used to store the context of a fault, but also to store the context of a thread that has been suspended.

edf30c06b4 New function mps_root_create_reg_masked applies a mask and pattern test to all words in registers and on the stack when scanning them. this supports tagged references in these locations. 
Consistently use the type "Word *" for pointers into the stack or into saved registers.
Remove TraceScanAreaTagged.

d5ea0fb20b Put the protection interface in prot.h, and the stack probe interface into sp.h, to make it easier to write the "porting" chapter of the manual.
