cb17267a8e Fix some checkleveldeep assertions: 
1. In GlobalsPrepareToDestroy, set arenaGlobals->defaultChain to NULL before calling ChainDestroy, to avoid a failed ChainCheck inside ControlFree.
2. In GlobalsPrepareToDestroy, set arenaGlobals->lock to NULL after destroying it, to avoid a failed LockCheck inside ControlFree.
3. In TraceIdMessagesCreate, set tsMessage[ti] and tMessage[ti] together to avoid a failed TraceIdMessagesCheck inside traceMessageInit.
4. In TracePostStartMessage, set tsMessage[ti] to NULL before calling MessagePost, to avoid a failed TraceStartMessageCheck inside ControlFree.
5. Ditto for TracePostMessage and tMessage[ti].

3260800a3a Mps br/timing traceanc.c review and polish: 
.whybuf.nul: the last char in the array must be NUL (even if there is another NUL earlier in the buffer).
Message Delete functions set sig to invalid, and call MessageFinish.
TraceIdMessagesDestroy uses message Delete functions.

eb1cca20e4 Mps br/timing z001989a.c: timca_remote -- traceidmessagescreate alloc remote control 
In low memory situations, ControlAlloc may be unable to allocate 
memory for GC messages.  This needs to work flawlessly, but is 
hard to test.  To simulate it for testing purposes, do macro-magic 
in traceanc.c, before the definition of TraceIdMessagesCreate.
Test all designed behaviour of TraceIdMessagesCreate failing.
See <design/message-gc#lifecycle>.

ac7a39432c Mps br/timing traceidmessages: create them at mps_arena_create time, 
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).
