Depending on how a user starts rdcd, rdcd will either have
full monitor/control capabilities or have just monitoring
capabilties.
The only 2 user ids allowed are "rdc" and root.

Initial testing include an "id test", which really just a

The google test code is included in this commit. It will
eventually be taken out and replaced with a pull from a google
external repo.
