channeldb: copy value from boltdb's Get instead of using it directly 
This can cause an intermittent panic otherwise if bbolt remaps itself
via munmap and mmap. From bbolt's documentation:

* Byte slices returned from Bolt are only valid during a transaction.
Once the transaction has been committed or rolled back then the memory
they point to can be reused by a new page or can be unmapped from
virtual memory and you'll see an unexpected fault address panic when
accessing it.

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
