Now that we're recommending inlining with client code and optimising with -O2 or -O3, we can't afford any bug introduced by the strict aliasing rule.

arenavm.c -- move chunk-return into new function "VMCompact".
(also, in VMArenaFinish, null out arena->primary in VMArenaFinish, so it is not left dangling).
arena.c, arenavm.c, mpm.h, mpmst.h, mpmtypes.h:
arena->class->compact: ArenaCompact, ArenaTrivCompact, VMCompact
trace.c -- traceReclaim calls ArenaCompact!

re-create them immediately after a trace sends its last message.
Store them, one per TraceId, in ArenaStruct. Cope correctly if they
cannot be created (ControlAlloc fails). Destroy them correctly on
mps_arena_destroy. See job001989 and design/message-gc#lifecycle
(not yet written).

job001784 leak, and allows some checking for other such leaks.

(tidyup) Move RulesGlobal to head of file; write instructions.
(tidyup) Move StringEqual into mpm.c (with StringLength); add AVER.
(cosmetic) Correct case of names: module-interface names begin
uppercase; local names begin lowercase. Tags should be C identifiers.

and mps_lib_EOF.
diag.c:
Diag is a buffer capable of holding a diagnostic.
FilterStream can buffer and filter diagnostics.
Rule is a selection rule for filtering diagnostics.
FilterOutput does output (but does not apply the rules yet).
DiagStream can be switched to either FilterStream() or mps_lib_stdout().

diag.c: support tagging of diagnostics, and avoid having to
say DIAG_STREAM every time, with new macros:
DIAG_SINGLEF, DIAG_FIRSTF, DIAG_MOREF, DIAG_END.
mpm.c: new WriteF_firstformat_v required by DIAG_MOREF.

Hope to fix in time, but for now I need DIAG-out to work, so switch
to printf (yes, really, I know, sorry).
Also, only do DIAG-out in variety.di, to avoid damage to .ci.
So for now, remove DIAG_WRITEF and DIAG from arenavm and trace.
To test, add DIAG_PRINTF in trace.
