net-p2p/bitcoin: Add an option to use newer BDB
Make the new option the default, so that when the port is recompiled it will link against BDB 5.x or 6.x (whichever is the default in the system). This will keep old wallet files readable and will not automatically convert them in an incompatible with BDB 4.8 way. Newly created wallet files will not be readable by Bitcoin Core versions linked with BDB 4.8. Next thing to consider is to remove the option to link against BDB 4.8 as this will remove the net-p2p/bitcoin -> databases/db48 dependency and will make it possible to ditch the latter, which is scheduled for removal from the ports collection on Apr 30 2018.

+The wallet is stored in a Berkeley database file (BDB) (usually
+~/.bitcoin/wallets/wallet.dat).
+
+Bitcoin Core can use either BDB 4.8, 5.x or 6.x to create and access the
+wallet file.
+
+Wallets created using BDB 4.8 are also accessible by BDB 5.x and 6.x.
+
+Wallets created using BDB 5.x or 6.x are not accessible by BDB 4.8.
+
+Opening and using a wallet created by 4.8 with a higher major version (5.x
+or 6.x) does not change its format, so it will still be accessible to 4.8
+afterwards. But encrypting an unencrypted wallet recreates it, so encrypting
+a 4.8 wallet with Bitcoin Core linked against BDB 5.x or 6.x will render it
+unreadable for Bitcoin Core linked against BDB 4.8.
+
+If you do not plan on copying the wallet file to another machine that uses
+BDB 4.8 then it is recommended to use the modern versions of BDB 5.x or 6.x.
