Bug#718272: BDB

Scott said: one more thing: debian is discussion dropping libdb (the db the node, but not the wallet, uses). That might force our hand as well: either ship and support upstream's included libdb or drop the node and just ship the wallet. libdb long-term security maintenance might be challenging.
