I would like to have the attached patch backported to 3-6. This change
massively improves the runtime performance of pivot table that has a
large source data range whose bottom part is mostly empty. Some users,
especially those who are used to Excel tend to do this, and without this
change, Calc hanges for about a few minutes when trying to launch field
popup window for the first time.
I know this is a large change, but IMO worth the backport. FWIW, all
the pivot table related unit tests pass after this change.
The patch is a collection of several different commits from the master
branch squashed into a single commit.
