fe1f07321b Fix makefile, accidentally broken by change 192512.

d31012f13a Implement mutatorcontextsp and mutatorcontextscan for platforms w3i3 and w3i6. 
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.

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.

3dbe56a8b7 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).

3f13486e08 Usability improvements for mmqa: 
* -i option (MPS_INCLUDE_DIR) now defaults to the code directory relative to the test harness location.
* -p option (PLATFORM) is now a six-character platform code for consistency with the rest of the MPS.
* New -v option (VARIETY) for specifying cool/hot/rash.
* -l option (MPS_LINK_OBJ) now defaults to the appropriate object file for the platform and variety.
* The object file is built automatically.
* If $Id$ of a test file is longer than 70 characters, cut characters out of the middle rather than off the end.
* Eliminate obsolete option -prod (MPS_PRODUCT).
* Support for FreeBSD.

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.
