In prep for most of the package funcs in net/interfaces to become methods in a long-lived netmon.Monitor that can cache things. (Many of the funcs are very heavy to call regularly, whereas the long-lived netmon.Monitor can subscribe to things from the OS and remember answers to questions it's asked regularly later) Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: Ie4e8dedb70136af2d611b990b865a822cd1797e5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
