[Libreoffice] Review Request: fdo#39023 for 3.4.* branch

Hi,

It would be great if somebody could review+push the attached patch to
3.4 branch(s). This is _not_ a problem in master.
Without this patch shared formula(s) would not be imported correctly in
builds from 3.4 branches.

Thanks to Markus (moggi) for debugging this to quite some level (and
also for fixing one part of the problem (defined name ranges) - that fix
is already reviewed+pushed).

Thanks & Regards,
Muthu Subramanian
