vis-marks: greatly simplify jumplist management

As far as I could tell from the code this was supposed to be a
fixed size LRU cache of sets of selection regions. The structure
had a maximum size member but it was never set or used.
Furthermore there was some very complicated management of 2
parallel sets of regions. Instead of that mess just treat the
cache as a circular buffer.

Note that this is really not that useful at the moment. While the
selection regions are saved and restored the editor mode is not.
Therefore the selection is visible but not in any way usable. That
will be fixed in the next commit.
