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.

This means that ThreadScan becomes identical on these two platforms and can be moved to thw3.c.
This means that thw3.h, thw3i3.c and thw3i6.c become redundant and can be deleted.

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.

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).

Use Failover in MVT and MVFF.
Test Failover in landtest.
Implementation of LandFindInZones for Freelist (untested).
Remove signature from RangeStruct so we can embed it without a space cost.

Add __attribute__((__format__(printf))) to functions that take a printf-compatible format string (when building using GCC or Clang), so that format string mistakes can be detected statically.

* New nmake file w3i6pc.nmk.
* New stack scanner ssw3i6pc.c supplies missing jump buffer definition.
* Some platform tests change from defined(MPS_PF_W3I6MV) to defined(MPS_OS_w3) && defined(MPS_ARCH_I6).
* Make reasonable changes to the source code to avoid warnings from Pelles C:
** Ensure that printf formats are consistent with arguments by using PRIuLONGEST and casting to ulongest_t.
** Use size_t for loop variables that index into arrays.
** Suppress "Consider changing type to 'size_t' for loop variable" warnings for the MPS core.

* Refactor nmake files so that a compiler-specific makefile is included; move Microsoft Visual C-specific options to mv.nmk.
* Add nmake files for Pelles (w3i3pc.nmk and pc.nmk).
* Rename spw3i3mv.c to spw3i3.c and spw3i6mv.c to spw3i6.c since these are also used by Pelles C.
* Make reasonable changes to the source code to avoid warnings from Pelles C:
** check results of function calls;
** avoid useless return values;
** undef max before defining it;
** ensure printf formats are checkable;
** move notreached() assertions to the end of blocks;
** suppress warnings in cases where the code shouldn't be changed ("Unreachable code", "Inline assembly code is not portable", "Structured Exception Handling is not portable").

Also switched to using platform specific Mutator Context code
so that we can read out the registers for instruction emulation
and stack scanning.
Builds on 64-bit but doesn't work because sem_init is unimplemented on
Mac OS X.
Not finished on 32-bit.

Some parts of this are still ragged, and would not normally pass review, but this is a massive improvement to the existing code.
