1a04431cff New modulefile prmcw3.c avoids duplication of code between prmcw3i3.c and prmcw3i6.c. 
Implement MutatorContextCheck on Windows. Add AVERT(MutatorContext, context) in PoolAccess and other functions.
Document initialization functions MutatorContextInitFault and MutatorContextInitThread and implement them on Windows.
Add a union discriminator to MutatorContextStruct on Windows so that we don't accidentally try to get the stack pointer from a fault context, or the exception address from a thread context.

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.

d0ae56d7dd Rename prot{i3,i6}.c to prmc{i3,i6}.c because these files are part of the protection mutator context module. 
Rename prmc{i3,i6}{fr,li,w3,xc}.c to prmc{fr,li,w3,xc}{i3,i6}.c for consistency of ordering of platform codes (OS before AR before CT).

be5db32120 Lockisheld implementation for generic ("ansi") locks. 
When CONFIG_THREAD_SINGLE is defined, use the generic lock module rather than compiling out all lock calls via lock.h. (Otherwise test cases that check LockIsHeld will fail.)
