/*

The canonical representation of a Vote for signing:

    |L|NNN...|h...|HHH...|

    L  length of network name (1 byte)
    N  name of network (max 255 bytes)
    h  height of block, varint encoded (1+ bytes)
    H  blockhash voted for height h

The wire format of a vote is usually simply a Signature.
The network name, height, and blockhash are omitted because
they are implied from context.  When it is not, e.g. evidence
for double-signing, the wire format is:

    |h...|HHH...|A...|SSS...|
