6e65f1ff18 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.

2d0f425428 Ensure that code of the form if (condition) statement; is split over two lines, so that it is possible to set a breakpoint on the statement in a debugger.
This change was agreed in 1997 (see <https://info.ravenbrook.com/project/mps/mail/1997/08/19/13-44/0.txt>), so it's about time it was implemented.

5f84d4c3db Clarify tracefix logic by unwinding the nested conditions.
Change the arena's chunk tree from a splay tree to an ordinary tree (so that it's not possible to accidentally splay it and leave it unbalanced).
New function TreeFindNext allows us to implement TractFirst and TractNext without having to splay the tree.
Make sure all operations on the chunk tree leave it balanced. But don't balance the tree directly in ChunkFinish() because this is only ever called in a loop where multiple chunks are being deleted from the tre. Instead use the sequence TreeToVine -- iterate and delete -- TreeBalance. The new macro TREE_DESTROY assists with this.
No need any more for ArenaIsReservedAddr, CHUNK_OF_ADDR, TRACT_OF_ADDR.
Update design documentation.

1243791d24 Ensure that djbench and gcbench compile on freebsd:
Link fmtdy with gcbench.
RESERVE_ALLOC in djbench ignores the return values from mps_reserve and mps_commit.
Don't include alloca.h -- alloca is in stdlib.h.
Rename start, finish to begin, end to avoid "local variable shadows global" error from gcc.
