Brad Fitzpatrick	a5e1f7d703	ipn/{ipnlocal,localapi}: add API to toggle use of exit node This is primarily for GUIs, so they don't need to remember the most recently used exit node themselves. This adds some CLI commands, but they're disabled and behind the WIP envknob, as we need to consider naming (on/off is ambiguous with running an exit node, etc) as well as automatic exit node selection in the future. For now the CLI commands are effectively developer debug things to test the LocalAPI.

Brad Fitzpatrick	aa084a29c6	ipn/ipnlocal: name the unlockOnce type, plumb more, add Unlock method This names the func() that Once-unlocked LocalBackend.mu. It does so both for docs and because it can then have a method: Unlock, for the few points that need to explicitly unlock early (the cause of all this mess). This makes those ugly points easy to find, and also can then make them stricter, panicking if the mutex is already unlocked. So a normal call to the func just once-releases the mutex, returning false if it's already done, but the Unlock method is the strict one. Then this uses it more, so most the b.mu.Unlock calls remaining are simple cases and usually defers.

Brad Fitzpatrick	5e7c0b025c	ipn/ipnlocal: add some "lockedOnEntry" helpers + guardrails, fix bug A number of methods in LocalBackend (with suffixed "LockedOnEntry") require b.mu be held but unlock it on the way out. That's asymmetric and atypical and error prone. This adds a helper method to LocalBackend that locks the mutex and returns a sync.OnceFunc that unlocks the mutex. Then we pass around that unlocker func down the chain to make it explicit (and somewhat type check the passing of ownership) but also let the caller defer unlock it, in the case of errors/panics that happen before the callee gets around to calling the unlock. This revealed a latent bug in LocalBackend.DeleteProfile which double unlocked the mutex.

Brad Fitzpatrick	7b34154df2	all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89] First we had Capabilities []string. Then https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a superset of Capabilities. Except we never really finished the transition inside the codebase to go all-in on CapMap. This does so. Notably, this coverts Capabilities on the wire early to CapMap internally so the code can only deal in CapMap, even against an old control server. In the process, this removes PeerChange.Capabilities support, which no known control plane sent anyway. They can and should use PeerChange.CapMap instead.

Sonia Appasamy	c58c59ee54	{ipn,cmd/tailscale/cli}: move ServeConfig mutation logic to ipn/serve Moving logic that manipulates a ServeConfig into recievers on the ServeConfig in the ipn package. This is setup work to allow the web client and cli to both utilize these shared functions to edit the serve config. Any logic specific to flag parsing or validation is left untouched in the cli command. The web client will similarly manage its validation of user's requested changes. If validation logic becomes similar-enough, we can make a serve util for shared functionality, which likely does not make sense in ipn.

Percy Wegmann	2d5d6f5403	ipn,wgengine: only intercept TailFS traffic on quad 100 This fixes a regression introduced with `993acf4` and released in v1.60.0. The regression caused us to intercept all userspace traffic to port 8080 which prevented users from exposing their own services to their tailnet at port 8080. Now, we only intercept traffic to port 8080 if it's bound for 100.100.100.100 or fd7a:115c:a1e0::53.
