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.

cf6c484a89 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.)

6f196185a1 Make shield assertions robust against deep checking -- when shieldcover is called from shieldraise there is one unsynced segment that has not yet been queued. record this fact in a new queuepending flag in the shield structure. 
Remove incorrect shield assertion "shield->depth == 0 || shield->suspended" -- depth may be increased without suspending the mutator if the segment did not need protecting.
