Add EphyHistoryService and helper classes

EphyHistoryService provides a high-level API to store history
information. It will processed by a worker thread using SQLite to
provide a fast, responsive service to the main UI.

Based on the code by Martin Robinson (mrobinson@igalia.com) and
Claudio Saavedra (csaavedra@igalia.com).
