calc: jumbo sheets on windows (never gonna happen)

i.e. very large spreadsheets of up to 16 million rows.

So I did some more investigation into this. In various places, we need to
accumulate things like row-heights and other things, numbers which, with
jumbo sheets, easily exceed 32-bits.


All over the place, we pass these values through
sal_uLong/sal_Long/long/unsigned long.

Which is 32-bits on Windows. Doh!

Honestly, the only solution I can think of (and one I confidently expect us
to reject), is that we declare a flag day, and search and replace
sal_Long/sal_uLong/long/unsigned long with a 64-bit type across the ENTIRE
code base.
