It was in SelfNode.Hostinfo anyway. The redundant copy was just
costing us an allocation per netmap (a Hostinfo.Clone).

Port 0 is interpreted, per the spec (but inconsistently among router
software) as requesting to map every single available port on the UPnP
gateway to the internal IP address. We'd previously avoided picking
ports below 1024 for one of the two UPnP methods (in #7457), and this
change moves that logic so that we avoid it in all cases.

Now mapSession has a bunch more fields and methods, rather than being
just one massive func with a ton of local variables.
So far there are no major new optimizations, though. It should behave
the same as before.
This has been done with an eye towards testability (so tests can set
all the callback funcs as needed, or not, without a huge Direct client
or long-running HTTP requests), but this change doesn't add new tests
yet. That will follow in the changes which flesh out the NetmapUpdater
interface.

When running in our github CI environment, curl sometimes hangs while closing
the download from the nodejs.org server and fails with INTERNAL_ERROR. This is
likely caused by CI running behind some kind of load balancer or proxy that
handles HTTP/2 incorrectly in some minor way, so force curl to use HTTP 1.1.

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.

I'd added a test case of deephash against a tailcfg.Node to make sure
it worked at all more than anything. We don't care what the exact
bytes are in this test, just that it doesn't fail. So adjust for that.
Then when we make changes to tailcfg.Node and types under it, we don't
need to keep adjusting this test.

It was added 2.5 years ago in c1dabd9436 but was never used.
Clearly that migration didn't matter.
We can attempt this again later if/when this matters.
Meanwhile this simplifies the code and thus makes working on other
current efforts in these parts of the code easier.

Serving the web client on the tailscale interface, while useful for
remote management, is also inherently risky if ACLs are not configured
appropriately. Switch the example to listen only on localhost, which is
a much safer default. This is still a valuable example, since it still
demonstrates how to have a web client connected to a tsnet instance.

The hardware version in `/proc/sys/kernel/syno_hw_version` does not map
exactly to versions in
https://github.com/SynoCommunity/spksrc/wiki/Synology-and-SynoCommunity-Package-Architectures.
It contains some slightly different version formats.
Instead, `/etc/synoinfo.conf` exists and contains a `unique` line with
the CPU architecture encoded. Parse that out and filter through the list
of architectures that we have SPKs for.

Previously we would use the Impersonate-Group header to pass through
tags to the k8s api server. However, we would do nothing for non-tagged
nodes. Now that we have a way to specify these via peerCaps respect those
and send down groups for non-tagged nodes as well.
For tagged nodes, it defaults to sending down the tags as groups to retain
legacy behavior if there are no caps set. Otherwise, the tags are omitted.
