vt-crypt: Implement Clone for Algorithms

[GoogleCodeExporter]

A common usage pattern arises from the need to handle crypto operations in a 
thread safe manner:

1. Create a crypto object (i.e. Algorithm), initialize it, and pass to a 
dependent component.
2. Dependent component clones crypto object into several copies to handle 
operations in thread-safe manner.

Algorithms presently do not support this usage pattern and should be modified 
to provide some means creating an exact copy such that both instances produce 
the same cryptographic output for equal inputs.
