puzzles: refactor and resync with upstream

This brings puzzles up-to-date with upstream revision
2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made
by me, including cursor-only Untangle and some compilation fixes
remain. Upstream code has been moved to its separate subdirectory and
future syncs can be done by simply copying over the new sources.

-Pearl
-<p>
-Draw a single closed loop by connecting together the centres of
-adjacent grid squares, so that some squares end up as corners, some as
-straights (horizontal or vertical), and some may be empty. Every
-square containing a black circle must be a corner not connected
-directly to another corner; every square containing a white circle
-must be a straight which is connected to <em>at least one</em> corner.
-<p>
-Drag between squares to draw or undraw pieces of the loop.
-Alternatively, left-click the edge between two squares to turn it on
-or off. Right-click an edge to mark it with a cross indicating that
-you are sure the loop does not go through it.
