This commit renames a bunch of files to try to make it a bit less confusing; protocol_ is now auth as they contained registration, auth and login/out flow protocol_.*_poll is now poll.go api.go and other generic handlers are now handlers.go Signed-off-by: Kristoffer Dalby <kristoffer@tailscale.com>
