Message:: update client state tracking in the gotd parent process The session process takes over the old state definitions under a new name ("session state"). The parent only needs to keep track of whether a client has been granted access, so it only uses two states: NEW, and ACCCESS_GRANTED which is set as soon as the auth process has granted repository access and before the session and repo_read/repo_write children are started. Because 'gotctl info' can no longer observe the session state remove support code for printing it. ok op@
