After the following changes are applied...

• change ~fiber_context and operator=() to have "requires: is empty" instead of cancelling
• add cancel() and cancel_from_any_thread() that calls the cancellation function if not empty
• replace thread termination when returning an empty fiber_context, with UB
  ...the SG1 design of fiber_context is ready for a TS vehicle
