Also introduce NewHeader and NewHeaderWith functions. The latter is
friendlier for create-and-initialize expressions, and can be used
in place of the old &Header{field: value, ...} syntax.
It should equal the one in the master copy found on beacon chain, except
if the master table doesn't have the shard (shard disowned), the local
leader should acknowledge this and signal the end of the shard by having
a committee proposal with empty leader and zero members.
