They changed a type in their SDK which meant others using the AWS APIs
in their Go programs (with newer AWS modules in their caller go.mod)
and then depending on Tailscale (for e.g. tsnet) then couldn't compile
ipn/store/awsstore.
Thanks to @thisisaaronland for bringing this up.

This change delays the first flush in the /watch-ipn-bus/ handler
until after the watcher has been successfully installed on the IPN
bus. It does this by adding a new onWatchAdded callback to
LocalBackend.WatchNotifications().
Without this, the endpoint returns a 200 almost immediatly, and
only then installs a watcher for IPN events. This means there's a
small window where events could be missed by clients after calling
WatchIPNBus().
Fixestailscale/corp#8594.

In order to be able to synthesize a new NetMap when a node expires, have
LocalBackend start a timer when receiving a new NetMap that fires
slightly after the next node expires. Additionally, move the logic that
updates expired nodes into LocalBackend so it runs on every netmap
(whether received from controlclient or self-triggered).

Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With
this change:
- Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded)
require either the WIP envknob or CapabilityTailnetLockAlpha.
- Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the
envknob / capability.
- Auxillary commands (ie: changing tka keys) require TKA to be initialized.
The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being
sent the capability or setting the envknob on tailscaled yourself.
I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock().

We want users to have the freedom to start tailscaled with `-no-logs-no-support`,
but that is obviously in direct conflict with tailnets that have network logging
enabled.
When we detect that condition, we record the issue in health, notify the client,
set WantRunning=false, and bail.
We clear the item in health when a profile switch occurs, since it is a
per-tailnet condition that should not propagate across profiles.
