ZFrame constructors should ensure the postcondition Position == 0

[sigiesec]

Currently, the ZFrame constructors accepting a string will position the ZFrame stream at the end. This makes the use confusing. It might even be considered a bug.

E.g. the following code will not work as expected (see https://stackoverflow.com/questions/42768088/c-sharp-zframe-data-extraction):

ZMessage msg = new ZMessage();   
msg.Add(new ZFrame("AABBCCDD"));            
var str = msg.PopString();

str will be empty afterwards.

Alternatives to changing the behaviour of the ZFrame constructors, this might be fixed by

1. Rewinding a ZFrame on ZMessage.Add
2. Rewinding a ZFrame on ZMessage.Pop

However, I think changing the behaviour of the ZFrame constructors is preferrable.
