As currently (for backward compatibility) the 0th
element of args is passed as a function, Noop
chaincode needs to threat this is its only argument.

- no need for function, only one kind of operation
  is supported by this chaincode
- exactly one argument is needed

Replaced ChaincodeStub with ChaincodeStubInterface to allow
unit testing of chaincode. MockStub added to emulate a real
chaincode without the storage or network requirements.
Unit test examples for chaincode_example02 to 05.

I have another changeset to address tables and certificates.

This allows applications to easily pass arbitrary blobs without having
to serialize them to strings.  At the same time, we also consolidate
the function argument to be part of the repeated bytes args.

For convenience and to simplify porting of existing chaincode to the
new argument format, we introduce helper functions in the shim which
cast between ([][]byte) and (string, []string).

This squashed changeset does the following:
 - It renames UUID to TXID in the code (Go/Java), in tests,
   in proto files, in all chaincode related files
 - It uses all the arguments of the chaincode to
   generate the TXID
