2aacdd3867 Using os-provided getopt_long where available, since it doesn't compile cleanly on os x. 
The getopt_long code promises that the argv array is const, but permutes it. (This problem is mentioned in the man page.) We have trouble getting this past our strict compiler options, especially under Xcode.

703c1ee5f5 New function mps_arena_configure provides keyword argument interface to changing the properties of an arena. 
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.

e00ab0e31b In mpmcheck, assert that stackprobedepth words will fit into a page, so that we find out if design.mps.sp.sol.depth.constraint is ever violated. 
Format methods must have bounded stack usage for stack probing to be effective, so document this in the manual (picking the arbitrary value 64 for the bound, which should be more than enough).
