This patch series implements analog tuner step increment/decrement as well as performs
cec-compliance tests for: select analog service, give tuner device status, and analog
step increment/decrement.  New tests where added for tuner step increment/decrement and
existing tests where refactored for select analog service and give tuner device status.

Changes made since v1:
  - Remove redundant error checking
  - Add circular wrap logic to tuner step increment/decrement
