Add deprecation notice to some UPPER_CASE enums.

The enumerators won't change, but the type name will change in 0.3.0.
Reasoning:
- Type names in toxcore start with an uppercase letter and either have at
  least one lowercase letter in them, or are less than 4 characters long.
- Constants consist of 4 or more uppercase letters or underscores.

By these rules, "DHT" is a type name, but "TOX_USER_STATUS" is a
constant. We provide Tox_User_Status as an alternative for now, and will
switch to that in 0.3.0, removing the UPPER_CASE versions.
