1. Being on the critical path is a property of the code location where the event is emitted, not of the event type, so indicate this using EVENT_CRITICAL macros rather than a field in the event table.
2. Compile out events on the critical path in hot varieties.
3. Remove TraceFixWhite event (redundant with TraceFixSeg).
4. No need for special handling of PoolFree event -- this are already skipped in hot varieties by dispatching directly to the pool class via PoolFreeMacro.

Split event ArenaAccess into ArenaAccessBegin and ArenaAccessEnd to avoid the need for the count field.
New events SegReclaim and SegScan.
Delete some redundant events: AMCFinish (PoolFinish), AMCFix, AMCFixForward, AMCFixInPlace (TraceFix), AMCGenCreate (GenInit), AMCGenDestroy (GenFinish), AMCInit (PoolInitAMC), AMCReclaim (SegReclaim), AMCScanBegin, AMCScanEnd (SegScan), ArenaWriteFaults (ArenaAccessBegin), PoolInitMV, TraceScanSeg (SegScan).
Add result code field to events ArenaAllocFail, CommitLimitSet, SegAllocFail.
Remove arena field from events PoolInitAMS, PoolInitMFS, PoolInitMVFF (already appeared in generic PoolInit event).

The MPS passes the number of system pools to the monitor via the ArenaCreate events, to avoid the monitor having to know how many this is.

Draw graphs for up to two different units using Axes.twinx.

Sort the events in batches so that, for example, we get PoolFinish before ArenaDestroy.
Emit ArenaDestroy event after finishing all its pools.
Add arena parameter to PoolFinish event.
Restore top-down logging of events (no need to order them the telemetry output, since the monitor sorts them).
Add comments for all the events used by the monitor.
Include the arena's name in the pool's name when there are multiple arenas.

In telemetry output, distinguish between labelling of (client) addresses and (MPS-internal) pointers, to avoid transgressing the distinction.
Add arena grain size, class, and serial number to ArenaCreate* events.
Add pool class and serial number to PoolInit event.

Update event format to 2.0.0 since telemetry format changed.
New macro EVENT_ANY_FIELDS allows consumers to determine the layout of the event header.
mpseventpy now analyzes the event layout (including padding bytes) and emits struct format specifications.
New program tool/monitor.py reads and unpacks a stream of telemetry events.

The fixEmergency method must have the same type as the fix method because of how they are used.
