This copies the existing go template frontend into very crude react
components that will be driven by a simple JSON api for fetching and
updating data. For now, this returns a static set of test data.
This just implements the simple existing UI, so I've put these all in a
"legacy" component, with the expectation that we will rebuild this with
more properly defined components, some pulled from corp.

3. Rename LocalClient.IncrementMetric to IncrementCounter to better

The Layered Service Provider (LSP) is a deprecated (but still supported)
mechanism for inserting user-mode DLLs into a filter chain between the
Winsock API surface (ie, ws2_32.dll) and the internal user-mode interface
to the networking stack.
While their use is becoming more rare due to the aforementioned deprecation,
it is still possible for third-party software to install their DLLs into
this filter chain and interfere with Winsock API calls. Knowing whether
this is happening is useful for troubleshooting.

The current router errors out when neither iptables nor nftables support is present. We
should fall back to the previous behaviour which we creates a dummy iptablesRunner.

See issue. This is a baby step towards passing through deltas
end-to-end from node to control back to node and down to the various
engine subsystems, not computing diffs from two full netmaps at
various levels. This will then let us support larger netmaps without
burning CPU.
But this change itself changes no behavior. It just changes a func
type to an interface with one method. That paves the way for future
changes to then add new NetmapUpdater methods that do more
fine-grained work than updating the whole world.

The read of the synced field for logging takes place outside the lock, and
races with other (locked) writes of this field, including for example the one

Implement naive update for Synology packages, using latest versions from
pkgs.tailscale.com. This is naive because we completely trust
pkgs.tailscale.com to give us a safe package. We should switch this to
some better signing mechanism later.
I've only tested this on one DS218 box, so all the CPU architecture
munging is purely based on docs.

Netcheck no longer performs I/O itself, instead it makes requests via
SendPacket and expects users to route reply traffic to
ReceiveSTUNPacket.
Netcheck gains a Standalone function that stands up sockets and
goroutines to implement I/O when used in a standalone fashion.
Magicsock now unconditionally routes STUN traffic to the netcheck.Client
that it hosts, and plumbs the send packet sink.
The CLI is updated to make use of the Standalone mode.

Instead of having updates replace the map polls, create
a third goroutine which is solely responsible for making
sure that control is aware of the latest client state.
This also makes it so that the streaming map polls are only
broken when there are auth changes, or the client is paused.

move the tailscale web client out of the cmd/tailscale/cli package, into
a new client/web package. The remaining cli/web.go file is still
responsible for parsing CLI flags and such, and then calls into
client/web. This will allow the web client to be hooked into from other
contexts (for example, from a tsnet server), and provide a dedicated
space to add more functionality to this client.
