[REVIEW-3-6 3-6-2] several patches for bugs in conditional formats/ ScRangeList

[Markus Mohrhard]

Hey,

I have several patches that are needed to fix bugs in conditional
formats. One of them is a MAB/regression with several duplicates.

They apply cleanly on 3-6 and you may squash them into one large
commit but it makes reviewing them even more complicated. I did not do
that yet because it makes reviewing even more difficult. They allow to
update ScRangeLists correctly when the cells are moved or deleted.
There is one small problem with updating moving only parts of one of
the ScRange entries but this will require more concept work to find
all corner cases and to implement this. These cases are not that
important and these patches here are already an improvement in this
direction.

Please apply them in the following order:

Nearly all of these patches are only changing ScRangeList and not
directly the conditional format code. I have some unit tests for
ScRangeList::UpdateReference and ScRangeList::DeleteArea in
sc/qa/unit/rangelst_test.cxx
