QSCC GetTransactionByID should return a Transaction  Envelope,
not a Transaction. The Envelope contains the signature and
Payload, which contains the transaction header and Transaction.

Clients will want the transaction header information when retrieving
the transaction.  They may also want the signature to verify that
the transaction hasn't changed since the time they submitted it.
The return type will change from Transaction proto to Envelope proto.

This changeset:
- Renames package ledger/util/db to ledger/util/leveldbhelper
- Implements a leveldb provider
  (that enables using same leveldb instance as a multiple logical dbs)
  in util package for being able to reuse across statedb, index,
  and later for historydb
- Implements a provider as a single point of invocation
  for managing multiple block storage
- Uses a single leveldb instance for block storage index
- Makes the structures other than providers as private
  to their respective packages

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

Just a reorg of the files in keeping with creation of
"common" and "orderer" package files with corresponding
import changes.

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