Brad Fitzpatrick cb4a2c00d1 ipn: remove unused Prefs.OSVersion and Prefs.DeviceModel
iOS and Android no longer use these. They both now (as of today)
use the hostinfo.SetFoo setters instead.

Brad Fitzpatrick 81269fad28 hostinfo: add SetOSVersion like SetDeviceModel, deprecate ipn.Prefs way
Turns out the iOS client has been only sending the OS version it first
started at. This whole hostinfo-via-prefs mechanism was never a good idea.
Start removing it.

Brad Fitzpatrick 3b3994f0db ipn{,/localapi,ipnlocal}: infer cert dir from state file location
This fixes "tailscale cert" on Synology where the var directory is
typically like /volume2/@appdata/Tailscale, or any other tailscaled
user who specifies a non-standard state file location.

This is a interim fix on the way to #2932.

Brad Fitzpatrick aae622314e tailcfg, health: add way for control plane to add problems to health check
So if the control plane knows that something's broken about the node, it can
include problem(s) in MapResponse and "tailscale status" will show it.
(and GUIs in the future, as it's in ipnstate.Status/JSON)

This also bumps the MapRequest.Version, though it's not strictly
required. Doesn't hurt.

In prep for other bug fixes & tests. It's hard to test when it was
intermingled into LocalBackend.authReconfig.

Now it's a pure function.

And rename variable 'uc' (user config?) to the since idiomatic
'prefs'.

David Crawshaw 9502b515f1 net/dns: replace resolver IPs with type for DoH
We currently plumb full URLs for DNS resolvers from the control server
down to the client. But when we pass the values into the net/dns
package, we throw away any URL that isn't a bare IP. This commit
continues the plumbing, and gets the URL all the way to the built in
forwarder. (It stops before plumbing URLs into the OS configurations
that can handle them.)

types/key: add a special key with custom serialization for control private keys (#2792)
* Revert "Revert "types/key: add MachinePrivate and MachinePublic.""

This reverts commit 61c3b98a24.

Signed-off-by: David Anderson <danderson@tailscale.com>

* types/key: add ControlPrivate, with custom serialization.

ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.

Josh Bleecher Snyder a666b546fb ipn/ipnlocal: log number of packet filters rather than entire filter
The number of packet filters can grow very large,
so this log entry can be very large.
We can get the packet filter server-side,
so reduce verbosity here to just the number of filters present.

Joe Tsai 9a0c8bdd20 util/deephash: make hash type opaque
The fact that Hash returns a [sha256.Size]byte leaks details about
the underlying hash implementation. This could very well be any other
hashing algorithm with a possible different block size.

Abstract this implementation detail away by declaring an opaque type
that is comparable. While we are changing the signature of UpdateHash,
rename it to just Update to reduce stutter (e.g., deephash.Update).

Brad Fitzpatrick 01e159b610 ipn/ipnlocal: save prefs to disk on UpdatePrefs
Regression from 6d10655dc3, which added
UpdatePrefs but didn't write it out to disk.

I'd planned on adding tests to state_test.go which is why I'd earlier
added 46896a9311 to prepare for making
such persistence tests easier to write, but turns out state_test.go
didn't even test UpdatePrefs, so I'm staying out of there.
Instead, this is tested using integration tests.
