Poller.C and Poller.c were duplicated for one caller. Add an accessor returning the receive-only version instead. It'll inline. Poller.Err was unused. Remove. Then Poller is opaque. The channel usage and shutdown was a bit sketchy. Clean it up. And document some things. Change-Id: I5669e54f51a6a13492cf5485c83133bda7ea3ce9 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
