This commit contains a series of post-merge fixes which include:
* ToBytes -> Encode
* As the former version doesn’t _require_ allocation of new slices *
* Store -> AddNextEntry
* To communicate to the caller that entries MUST be added
in order
* Several grammar, spacing, spelling and gofmt fixes.
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.
The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.
