Brad Fitzpatrick	86e0f9b912	net/ipset, wgengine/filter/filtertype: add split-out packages This moves NewContainsIPFunc from tsaddr to new ipset package. And wgengine/filter types gets split into wgengine/filter/filtertype, so netmap (and thus the CLI, etc) doesn't need to bring in ipset, bart, etc. Then add a test making sure the CLI deps don't regress.

Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	7 months ago

Brad Fitzpatrick	ebc552d2e0	health: add Tracker type, in prep for removing global variables This moves most of the health package global variables to a new `health.Tracker` type.
