Bug 1108104 part 1 - Remove mFixedContainingBlock.  Make GetAbsoluteContainingBlock() check for an ancestor with the right frame type instead.  r=roc
Bug 1108104 part 2 - Move incremental reflow hack from nsSimplePageSequenceFrame::Reflow to nsTableOuterFrame. This is to avoid breaking pages that don't even use tables.  r=roc
Bug 1108104 part 3 - Deal with the placeholder being on a different page than the out-of-flow frame.  r=roc
Bug 1108104 part 4 - Don't use the current next-sibling as a reference point where to continue the loop, since that frame may be pushed if it's also the next-in-flow.  Instead, use the frame from the last iteration (the prev-sibling) and query its (potentially new) next-sibling.  r=roc
Bug 1108104 part 5 - Don't report a reflow as NS_FRAME_NOT_COMPLETE when it's actually complete.  Because it will give the frame the wrong BSize.  r=roc
