QPID-3913: Add functionality to upgrade bdbstore automatically on broker start-up. Store message content using single chunk. Change store version to 6. Remove implementations of tuple bindings for previous versions.

Applied patch from Phil Harvey<phil@philharveyonline.com> Oleksandr Rudyy<orudyy@gmail.com>

- * This is a simple BerkeleyDB Store upgrade tool that will upgrade a V4 Store to a V5 Store.
- *
- * Currently upgrade is fixed from v4 -> v5
- *
- * Improvments:
- * - Add List BDBMessageStore.getDatabases(); This can the be iterated to guard against new DBs being added.
- * - A version in the store would allow automated upgrade or later with more available versions interactive upgrade.
- * - Add process logging and disable all Store and Qpid logging.
