Adds an EOF flag to data chunks to avoid using []byte("EOF") as end (due to potential false positives).
Furthermore, a few cleanups are done:
- Add TODOs for initial git changes
- Add missing file headers
- Fix typo for license (was licence)
- Fix make wire target
This change introduces the concept of a principal (abstraction of call identity), and adds a new service account type principal. Also adds support for different tokens (session, PAT, SAT, OAuth2) and adds auth.Session which is being used to capture information about the caller and call method.
