8bc2be4de1
After this change, we have PLDHashTable::ShallowSizeOf{In,Ex}cludingThis(),
which don't do anything to measure children. (They can be combined with
iteration to measure children.)
This patch also removes the PL_DHashTableSizeOf{In,Ex}cludingThis() functions.
They're not necessary because the methods can be used instead.
Finally, the patch deliberately converts some SizeOfExcludingThis() calls to
SizeOfIncludingThis(). These are all done on heap pointers so this change is
valid.
