Cas Cremers f9a34f4de5 BUGFIX: Updating hashfunction usage in protocol files to new conventions.
After the new function implementation, the 'Function' type is no longer one-way by default.
However, many protocol description files relied on this implicit assumption.
The solution is to use 'hashfunction' declarations instead to model one-wayness.

Original bug report by Binh Thanh Nguyen.
