Allow PGP signature to be read from sync database

Add a new field to the package struct to hold PGP information and
instruct db_read to pick it up from the database. It is currently unused
internally but this is the first step.

Due to the fact that we store the PGP sig as binary data, we need to store
both the data and the length so we have a small utility struct to assist us.
