Introduce "Non-reentrant time" radio button

Browse Source 
Add to the statistics view an option for "Non-reentrant
time", which displays the count of and time spent in zone
events which were the only appearances (at that time) of
their zones on their threads' stacks.

Besides the GUI changes, this involves:

- Introducing a tri-state accumulation mode to replace the
boolean "self time":  now there's "Self time only",
"Child time", and "Non-reentrant time".

- Removing the separate "selfTotal" from SrcLocZonesSlim,
making "total" represent whichever of the now three options
is active, which in turn requires keeping track of the
accumulation mode in StatisticsCache and invalidating that
cache when the accumulation mode changes.
