14cf9d4890 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].

f906187add iterating over segments using the pool and segment rings, rather than scanning the tract table, which may be full of irrelevant tracts, especially when non-gc pools are large. see <https://info.ravenbrook.com/mail/2014/01/25/12-16-09/0/>.

870bea6e2d Avoid undefined behaviour in ring_elt by using parent (and thus offsetof) instead of deferencing a null pointer. add missing typedef for rememberedsummaryblockstruct. update ring design accordingly.

920390c31a Mps br/timing: rename mps_alert_collection_*. the correct term for when a new mps operation begins is "begin", and when it ends is "end". (whereas several starts/stops may happen during a single mps operation).

9287a84bc8 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.

3a6f6d10f2 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>.

380ab1ec56 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).
