The golang tests in different packages are run in parallel
(unless controlled by special flag `-p=1`).
To avoid collision among tests of different packages,
use different folders that are used to store ledger contents.

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

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.
