[PATCH libreoffice-4-0] bnc#802350: Cell validation is not a special (cell) content.

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/2128

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/28/2128/1

bnc#802350: Cell validation is not a special (cell) content.

Cell validation is stored as cell attributes which are stored with
columns not with cells.  When HasSpecialContent() is true, it flags
the *cell* not empty, which in turns causes AddTextAndValueCell to
iterate over every single cell position for all repeated columns
and rows.  That can very very slow when the number of repeated rows
is very high.

Since cell validation is stored with columns, skipping empty cells
even when they have cell validation settings set won't cause any
issues, and all cell validation settings are imported correctly even
after this change.

With the test document I have (confidential), this change alone reduces
the load time from 30 seconds to 0.3 seconds.

(cherry picked from commit f6acfb5fe41fb166b5b588ec73e2e9331489c632)
