yyforyongyu 65a2f3ac81 channeldb: add optional meta and migration30 
This commit enables the db to run optional migrations that are specified
by config flags. To achieve this, an optional meta is introduced to
manage the optional migrations. We distinguish the two types of
migrations here so it's easier to manage them for the concern a future
migration can cause trouble for us to determine the db version if we
don't.

channeldb

Build Status MIT licensed GoDoc

The channeldb implements the persistent storage engine for lnd and generically a data storage layer for the required state within the Lightning Network. The backing storage engine is boltdb, an embedded pure-go key-value store based off of LMDB.

The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
