Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

This PR adds validations for the new new funnel/serve

1. There is always a single config for one port (bg or fg).
2. Foreground configs under the same port cannot co-exists (for now).
3. Background configs can change as long as the serve type is the same.

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.

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.

We already had a path on the web client server struct, but hadn't
plumbed it through to the CLI. Add that now and use it for Synology and
QNAP instead of hard-coding the path. (Adding flag for QNAP is
tailscale/tailscale-qpkg#112) This will allow supporting other
environments (like unraid) without additional changes to the client/web
package.
Also fix a small bug in unraid handling to only include the csrf token

This uses the new react-based web client for all builds, not just with
the --dev flag.
If the web client assets have not been built, the client will serve a
message that Tailscale was built without the web client, and link to
build instructions. Because we will include the web client in all of our
builds, this should only be seen by developers or users building from
source. (And eventually this will be replaced by attempting to download
needed assets as runtime.)
We do now checkin the build/index.html file, which serves the error
message when assets are unavailable. This will also eventually be used
to trigger in CI when new assets should be built and uploaded to a
well-known location.

In b987b2ab18 (2021-01-12) when we introduced sharing we mapped
the sharer to the userid at a low layer, mostly to fix the display of
"tailscale status" and the client UIs, but also some tests.
The commit earlier today, 7dec09d169, removed the 2.5yo option
to let clients disable that automatic mapping, as clearly we were never
getting around to it.
This plumbs the Sharer UserID all the way to ipnstatus so the CLI
itself can choose to print out the Sharer's identity over the node's
original owner.
Then we stop mangling Node.User and let clients decide how they want
to render things.
To ease the migration for the Windows GUI (which currently operates on
tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus),
a new method Node.SharerOrUser is added to do the mapping of
Sharer-else-User.

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.
