Logging: don't emit ANSI color codes if !isatty()

This CL makes a bunch of changes to logging:
- Move the core logic to a dedicated .cc file
- Add a timestamp in front of the logs (wall time % 1000)
  to better debug across processe (not in the logcat case)s.
- Enables the coloured output only when stderr is a tty.
- Fixes the truncation of the filename to be left-truncated
  rather than right-truncated (which is more useful in general).
