All of these are unique control setups for leg controls. The most general advice, is to find a way to make them all work individually, and then create each joint chain, and have it affect a chain that the geometry is bound to. Then the animator can choose which type of control to use.

Some general ideas for the solutions:
-bendy leg: given that his curve is so smooth and continuous, it's probably a simply ikSpline setup.
-lockable knees have more to do with adjusting the length of joints. So, setting up controls and inputs that drive, say the X translation (in an XYZ or XZY orientation) of the necessary joints.

I'm not really sure what you're specifically looking for or mean by 'soft IK' 'knee swivel' or knee release.

Hope this helps some...

soft Ik to have a limb with no POP when straight.

knee realese, allow you to easily pin the knee position....
