[REVIEW][3-5][3-4] fdo#41712 SwFlowFrm::pPrecede regression

[Michael Stahl]

apparently a SwFlowFrm::pPrecede was introduced, turning the SwFlowFrm
list from a singly linked list to a doubly linked list, without much
thought given to the additional invariants that need to be maintained;
these patches should fix that up and should go into libreoffice-3-4 and
libreoffice-3-5:
