This permits other programs (in other repos) to conditionally
import ipn/store/awsstore and/or ipn/store/kubestore and have them
register themselves, rather than feature/condregister doing it.

The `put` callback runs on a different goroutine to the test, so calling
t.Fatalf in put had no effect. `drain` is always called when checking what
was put and is called from the test goroutine, so that's a good place to
fail the test if the channel was too full.

https://github.com/tailscale/tailscale/pull/17346 moved the kube and aws
arn store initializations to feature/condregister, under the assumption
that anything using it would use kubestore.New. Unfortunately,
cmd/k8s-proxy makes use of store.New, which compares the `<prefix>:`
supplied in the provided `path string` argument against known stores. If
it doesn't find it, it fallsback to using a FileStore.
Since cmd/k8s-proxy uses store.New to try and initialize a kube store in
some cases (without importing feature/condregister), it silently creates
a FileStore and that leads to misleading errors further along in
execution.
This fixes this issue by importing condregister, and successfully
initializes a kube store.

The Tailscale CLI is the primary configuration interface and as such it
is used in scripts, container setups, and many other places that do not
have a terminal available and should not be made to respond to prompts.
The default is set to false where the "risky" API is being used by the
CLI and true otherwise, this means that the `--yes` flags are only
required under interactive runs and scripts do not need to be concerned
with prompts or extra flags.

In Dec 2021 in d3d503d997 I had grand plans to make exit node DNS
cheaper by using HTTP/2 over PeerAPI, at least on some platforms. I
only did server-side support though and never made it to the client.
In the ~4 years since, some things have happened:
* Go 1.24 got support for http.Protocols (https://pkg.go.dev/net/http#Protocols)
and doing UnencryptedHTTP2 ("HTTP2 with prior knowledge")
* The old h2c upgrade mechanism was deprecated; see https://github.com/golang/go/issues/63565
and https://github.com/golang/go/issues/67816
* Go plans to deprecate x/net/http2 and move everything to the standard library.
So this drops our use of the x/net/http2/h2c package and instead
enables h2c (on all platforms now) using the standard library.
This does mean we lose the deprecated h2c Upgrade support, but that's
fine.
If/when we do the h2c client support for ExitDNS, we'll have to probe
the peer to see whether it supports it. Or have it reply with a header
saying that future requests can us h2c. (It's tempting to use capver,
but maybe people will disable that support anyway, so we should
discover it at runtime instead.)
Also do the same in the sessionrecording package.

Saves 328 KB (2.5%) off the minimal binary.
For IoT devices that don't need MagicDNS (e.g. they don't make
outbound connections), this provides a knob to disable all the DNS
functionality.
Rather than a massive refactor today, this uses constant false values
as a deadcode sledgehammer, guided by shotizam to find the largest DNS
functions which survived deadcode.
A future refactor could make it so that the net/dns/resolver and
publicdns packages don't even show up in the import graph (along with
their imports) but really it's already pretty good looking with just
these consts, so it's not at the top of my list to refactor it more
soon.
Also do the same in a few places with the ACME (cert) functionality,
as I saw those while searching for DNS stuff.

When I added dependency support to featuretag, I broke the handling of
the non-omit build tags (as used by the "box" support for bundling the
CLI into tailscaled). That then affected depaware. The
depaware-minbox.txt this whole time recently has not included the CLI.
So fix that, and also add a new depaware variant that's only the
daemon, without the CLI.

Otherwise they're uselessly imported by tsnet applications, even
though they do nothing. tsnet applications wanting to use these
already had to explicitly import them and use kubestore.New or
awsstore.New and assign those to their tsnet.Server.Store fields.
