New keyword arguments MPS_KEY_ARENA_COMMIT_LIMIT and MPS_KEY_SPARE_ARENA_COMMIT_LIMIT can be passed to mps_arena_create_k or mps_arena_configure.
Deprecate mps_arena_commit_limit_set and mps_arena_spare_commit_limit_set.

Remove hack from rnd_grain -- this was covering up a bug.
Base the AMC "large" segment determination on the requested object size, not the (rounded up) segment size.
Assert in the case where largeSize < extendBy: this has bad space performance.

New function ProtGranularity returns the protection granularity of the operating system. (On all currently supported operating systems this is the same as the granularity of memory mapping returned by VMPageSuze, but it's important to separate these concepts.) MPMCheck asserts that the granularity of memory mapping is a multiple of the granularity of protection.
Client arena supports MPS_KEY_ARENA_GRAIN_SIZE.
Some of the test cases set the arena grain size.

Set the commit limit in amcss and amcsshe so that we test that the MPS can live in a tight memory limit.
Don't try to detect when the MPS has made a "dynamic" collection. This is not reliable or maintainable.

Smoke tests for AMCZ -- add it to amcss, amcsshe, amcssth, finaltest and walkt0.
Smoke tests for LO -- add it to walkt0.
Fix finaltest for AMC and AWL -- need to allocate in generation 0 to get prompt finalization. (Also fix MMQA test function/51.c.)

* 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").

1. "make test" now reports the name of the test case before running it, so that when you look back through the test output you can see which test case failed.
2. "make test" now collects the standard output from all the tests to a log file in /tmp, so that this does not clutter the user's terminal, and so that nothing is lost if the output exceeds the terminal's scrollback.
3. Each test case now prints a success message ("Conclusion: Failed to find any defects.") to standard output (not standard error) so that these messages do not clutter up the terminal when running "make test".
4. Each test case now uses its result code (not the printed message) to indicate whether it succeeded or failed.
5. More of the diagnostic messages from the test cases now start by printing argv[0] so that it is easier to tell which test case was running.

function; MPS calls it synchronously on collection start/stop
(immediately after posting start/stop message). The callback
receives two ints: alertcode (start|stop; see mps.h), and whycode
(trace->why). Note: callback is also called for heap walk
start/stop.
amcss.c: show start/stop alerts.

- Keep counts of both collection start messages and collection end
messages. Upon receipt of these messages, format the collection
start/end reports as 'brackets' (makes it easier to see whether
allocation continues during the collection or not).
- If mps_collections has changed, report() messages before doing
anything else.
- (source code clarity) Guess that the naked "4" in the
mps_arena_has_addr test means "hitsWanted", and label it.
