Add all formats common to a and b to a, add b's refs to a and destroy b.
If check is set, nothing is modified and it is only checked whether the formats are compatible. If empty_allowed is set and one of a,b->nb is zero, the lists are merged; otherwise, 0 (for nonmergeability) is returned.

Merge the formats lists if they are compatible and update all the references of a and b to point to the combined list and free the old lists as needed.
The combined list usually contains the intersection of the lists of a and b.
Both a and b must have owners (i.e. refcount > 0) for these functions.
