ooo33gsl13: #i115906# obtain correct data range for external references

* Apparently ScTable::GetFirstDataPos() never worked as intended and selected
the first non-empty row of the first non-empty column instead of also taking
following columns into account where non-empty rows may be on top of that.
* Caller of ScDocument::ShrinkToDataArea() must check the return value, if
false there is no data in the area passed and the values obtained may be out
of bounds, not in order or unmodified.
* In ScExternalRefMgr a call of ScDocument::ShrinkToUsedDataArea() was
intended instead of ScDocument::ShrinkToDataArea(). For this changed the
return of ShrinkToUsedDataArea() to flag if there is any data and added an
out parameter to flag if the area was shrunk.
* Sanitized arguments and slightly optimized ScTable::ShrinkToUsedDataArea()
to not have to check for >0 and <MAX on each iteration.
