Brad Fitzpatrick 67396d716b ipn/ipnlocal: remove defensiveness around not having a magicsock.Conn
We always have one. Stop pretending we might not.

Instead, add one early panic in NewLocalBackend if we actually don't.

Brad Fitzpatrick b8a4c96c53 wgengine: remove LinkChange method from Engine interface
It was only used by Android, until
https://github.com/tailscale/tailscale-android/pull/131
which does the call to the netMon directly instead.

Brad Fitzpatrick 727b1432a8 wgengine: remove SetNetInfoCallback method from Engine
LocalBackend can talk to magicsock on its own to do this without
the "Engine" being involved.

(Continuing a little side quest of cleaning up the Engine
interface...)

Brad Fitzpatrick 343c0f1031 wgengine{,/netstack}: remove AddNetworkMapCallback from Engine interface
It had exactly one user: netstack. Just have LocalBackend notify
netstack when here's a new netmap instead, simplifying the bloated
Engine interface that has grown a bunch of non-Engine-y things.
(plenty of rando stuff remains after this, but it's a start)

Brad Fitzpatrick 39ade4d0d4 tstest/integration: add start of integration tests for incremental map updates
This adds a new integration test with two nodes where the first gets a
incremental MapResponse (with only PeersRemoved set) saying that the
second node disappeared.

This extends the testcontrol package to support sending raw
MapResponses to nodes.

Brad Fitzpatrick 7c1ed38ab3 ipn/ipnlocal: fix missing controlknobs.Knobs plumbing
I missed connecting some controlknobs.Knobs pieces in 4e91cf20a8
resulting in that breaking control knobs entirely.

Whoops.

The fix in ipn/ipnlocal (where it makes a new controlclient) but to
atone, I also added integration tests. Those integration tests use
a new "tailscale debug control-knobs" which by itself might be useful
for future debugging.

Brad Fitzpatrick 42072683d6 control/controlknobs: move ForceBackgroundSTUN to controlknobs.Knobs
This is both more efficient (because the knobs' bool is only updated
whenever Node is changed, rarely) and also gets us one step closer to
removing a case of storing a netmap.NetworkMap in
magicsock. (eventually we want to phase out much of the use of that
type internally)

Brad Fitzpatrick 4e91cf20a8 control/controlknobs, all: add plumbed Knobs type, not global variables
Previously two tsnet nodes in the same process couldn't have disjoint
sets of controlknob settings from control as both would overwrite each
other's global variables.

This plumbs a new controlknobs.Knobs type around everywhere and hangs
the knobs sent by control on that instead.

Brad Fitzpatrick d050700a3b wgengine/magicsock: make peerMap also keyed by NodeID
In prep for incremental netmap update plumbing (#1909), make peerMap
also keyed by NodeID, as all the netmap node mutations passed around
later will be keyed by NodeID.

In the process, also:

* add envknob.InDevMode, as a signal that we can panic more aggressively
  in unexpected cases.
* pull two moderately large blocks of code in Conn.SetNetworkMap out
  into their own methods
* convert a few more sets from maps to set.Set

Brad Fitzpatrick 0396366aae cmd/testwrapper/flakytest: don't spam stderr in Mark when not under wrapper
If the user's running "go test" by hand, no need to spam stderr with
the sentinel marker. It already calls t.Logf (which only gets output
on actual failure, or verbose mode) which is enough to tell users it's
known flaky. Stderr OTOH always prints out and is distracting to
manual "go test" users.

David Anderson 0909e90890 util/lru: replace container/list with a custom ring implementation
pre-generics container/list is quite unpleasant to use, and the pointer
manipulation operations for an LRU are simple enough to implement directly
now that we have generic types.

With this change, the LRU uses a ring (aka circularly linked list) rather
than a simple doubly-linked list as its internals, because the ring makes
list manipulation edge cases more regular: the only remaining edge case is
the transition between 0 and 1 elements, rather than also having to deal
specially with manipulating the first and last members of the list.

While the primary purpose was improved readability of the code, as it
turns out removing the indirection through an interface box also speeds
up the LRU:

       │ before.txt  │              after.txt              │
       │   sec/op    │   sec/op     vs base                │
