Add a new ledger blockstorage index for History
that will map (blocknum,trannum) to the file storage
location for this block transaction

This index will be used for the API  GetTransactionsForKey()
for (chaincode1,key1).  It will do a key range query on chaincode1~key1
to pick up all chaincode1~key1 records.  Results will indicate
the set of (blocknum,trannum) transactions that updated this key.

This commit fixes the ledger code as per new transaction structure.
Also removed the explicit dependency on the msp security code by moving
the code to a separate testutil for a better reuse.

NOTE - Removing of old proto.Transaction is the cause for
the large change set. It affects chaincode framework and
all users of the framework such as endorser, system chaincodes,
unit tests etc.

Transaction2 is renamed to Transaction.
Response2 is renamed to Response.
Message2 is renamed to Message.

The changes are fully described in
    https://jira.hyperledger.org/browse/FAB-1198



Summary
=======
   . Remove old Transaction and rename Transaction2
   . Cleanup of Chaincode protobuf message
   . Add TxID for SDK and higher layers to optionally
     set (currently errors if not set)

ChaincodeMessage removes QUERY and QUERY_CHAINCODE enums.

Shim interface does not enforce Query or QueryChaincode.

chaincode_example02 and 05 implement Query function via
the Invoke implementation.

The "noop" system chaincode is removed
   . it was using Transaction which is not an endorser
     artifact any longer
   . there are many system chaincodes to that thoroughly
     test sys chaincode functions

A final cleanup of removing unused messages and renaming
"2" suffixed protos needs to be done as a final cleanup
