Function signatures are not validated for function references as structure members

Structure members which are function references do not support any form of 
signature validation; i.e. it is possible to pass a non-conforming function to 
the constructor or member-mutator of the structure and thereby cause runtime 
chaos.

Add function signature data to the structure metadata so that it is possible to 
validate (both statically and, if necessary, dynamically) that functions 
assigned to function reference structure members provide the correct signature.
