dbwrapper: Pass parent CDBWrapper into CDBBatch and CDBIterator

Browse Source 
Zcash: Makes future extensions easier.

Original description (when this was introduced upstream):

Pass parent wrapper directly instead of obfuscation key. This
makes it possible for other databases which re-use this code
to use other properties from the database.

Add a namespace dbwrapper_private for private functions to be used
only in dbwrapper.h/cpp and dbwrapper_tests.
