In this commit, a new channel-ID index is added to the tower client db with the help of a migration. This index holds a mapping from a db-assigned-ID (a uint64 encoded using BigSize encoding) to real channel ID (32 bytes). This mapping will help us save space in future when persisting references to channels.

// ChannelID is a series of 32-bytes that uniquely identifies all channels
|
|
// within the network. The ChannelID is computed using the outpoint of the
|
|
// funding transaction (the txid, and output index). Given a funding output the
|
|
// ChannelID can be calculated by XOR'ing the big-endian serialization of the
|
|
// txid and the big-endian serialization of the output index, truncated to
|
|
// 2 bytes.
