This commit changes the definition of the constraints in the ChannelConstraints struct to specify that these are all constraints the *owner* of the set of constraints must *never violate*. This is done to make it easier to check that a particular node is not violating any constraint for a gien update, as before it could violate constraints found both in its local and the remote contraints.
channeldb
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
