aea2ed3811 Handle deletion of arenas and pools (they often get recreated at the same addresses so this is vital). 
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.

c3a7104eff Label the time series in the monitor. 
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.

5cc5bb5922 Don't store booleans as bit-fields in event structures: this makes it impossible to automatically unpack them using python's struct module. (the only event where this actually saved any space was poolinitmvff!) 
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.
