ArenaSpareCommitExceeded changed to ArenaPurgeSpare so that the arena can properly reduce the amount of spare memory when setting the commit limit etc.
pagesMarkAllocated promptly unmaps page table pages in its error path.
Miscellaneous clarifications and extra checking.

Not quite working yet. This code fails to unmap unused page table pages, and so triggers an assertion at chunk finish.

Always recording events into buffers, but only writing them to the telemetry stream if they're enabled.

Abolishing event formats. Each event now has its own structure.
Event parameters are now written directly into the event buffer, rather than being copied twice.

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!

tract.c -- fix more ChunkCache defects:
- drop never-read chunkCache->pageTableBase and pageTableLimit fields: they were used for ChunkOfSeg(), back when each SegStruct was actually a PageStruct is some chunk's PageStructTable; see VMArenaChunkOfSeg() in //info.ravenbrook.com/project/mps/branch/2001-08-13/trunk/src/arenavm.chttps://github.com/Ravenbrook/mps/issues/46
- there's no need for arena to initialise the chunk cache; this allows en/decache functions to be local to tract.c (ie. declared static)

Messages:
- _gc_start and _gc now always ControlAlloc'd, new lifecycle, much better code. Fixes job001989.
- New test zmess, which tests generating and getting MPS messages. Tests job001989, and also job001658 (subsumes fin1658a.c).
- New file traceanc.c, for ancillary code extracted from trace.c.
- Diag (.variety.di) at ArenaDestroy, say if message queue non-empty.
Randomize() and rnd() now much better seeding, improved (more random) generator, thorough verification, faster.
New test zcoll (incomplete), which tests MPS collections, their timing, and feedback about them.
MPS_ALERT_COLLECTION_START/STOP renamed as MPS_ALERT_COLLECTION_BEGIN/END

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).

function; MPS calls it synchronously on collection start/stop
(immediately after posting start/stop message). The callback
receives two ints: alertcode (start|stop; see mps.h), and whycode
(trace->why). Note: callback is also called for heap walk
start/stop.
amcss.c: show start/stop alerts.

This change will be integrated but ignored (-ay) to the gg-epcore/union sources, so that they retain HopeNames.
