checkheads: extract obsolete post processing in its own function
The checkheads function is long and complex, extract that logic in a subfunction
is win in itself. As the comment in the code says, this postprocessing is
currently very basic and either misbehave or fails to detect valid push in many
cases. My deeper motive for this extraction is to be make it easier to provide
extensive testing of this case and strategy to cover them. Final test and logic
will makes it to core once done.
