clientupdate: add support for QNAP (#10179)
Use the `qpkg_cli` to check for updates and install them. There are a
couple special things about this compare to other updaters:
* qpkg_cli can tell you when upgrade is available, but not what the
  version is
* qpkg_cli --add Tailscale works for new installs, upgrades and
  reinstalling existing version; even reinstall of existing version
  takes a while

09de240934 ipn/ipnlocal: allow connecting to local web client
The local web client has the same characteristic as tailscale serve, in
that it needs a local listener to allow for connections from the local
machine itself when running in kernel networking mode.

This change renames and adapts the existing serveListener to allow it to
be used by the web client as well.

3496d62ed3 ipn/ipnlocal: add empty address to the app-connector localNets set
App connectors handle DNS requests for app domains over PeerAPI,
but a safety check verifies the requesting peer has at least permission
to send traffic to 0.0.0.0:53 (or 2000:: for IPv6) before handling the DNS
request. The correct filter rules are synthesized by the coordination server
and sent down, but the address needs to be part of the 'local net' for the
filter package to even bother checking the filter rules, so we set them here.
See: https://github.com/tailscale/corp/issues/11961 for more information.

6b956b49e0 client/web: add some security checks for full client
Require that requests to servers in manage mode are made to the
Tailscale IP (either ipv4 or ipv6) or quad-100. Also set various
security headers on those responses.  These might be too restrictive,
but we can relax them as needed.

Allow requests to /ok (even in manage mode) with no checks. This will be
used for the connectivity check from a login client to see if the
management client is reachable.

658971d7c0 ipn/ipnlocal: serve web client on quad100 if enabled
if the user pref and nodecap for the new web client are enabled, serve
the client over requests to 100.100.100.100.  Today, that is just a
static page that lists the local Tailcale IP addresses.

For now, this will render the readonly full management client, with an
"access" button that sends the user through check mode.  After
completing check mode, they will still be in the read-only view, since
they are not accessing the client over Tailscale.

Instead, quad100 should serve the lobby client that has a "manage"
button that will open the management client on the Tailscale IP (and
trigger check mode). That is something we'll fix in a subsequent PR in
the web client code itself.

89953b015b ipn/ipnlocal,client/web: add web client to tailscaled
Allows for serving the web interface from tailscaled, with the
ability to start and stop the server via localapi endpoints
(/web/start and /web/stop).

This will be used to run the new full management web client,
which will only be accessible over Tailscale (with an extra auth
check step over noise) from the daemon. This switch also allows
us to run the web interface as a long-lived service in environments
where the CLI version is restricted to CGI, allowing us to manage
certain auth state in memory.

ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for
ios builds to satisfy ios restriction from adding "text/template"
and "html/template" dependencies.

95671b71a6 ipn, safesocket: use Windows token in LocalAPI
On Windows, the idiomatic way to check access on a named pipe is for
the server to impersonate the client on its current OS thread, perform
access checks using the client's access token, and then revert the OS
thread's access token back to its true self.

The access token is a better representation of the client's rights than just
a username/userid check, as it represents the client's effective rights
at connection time, which might differ from their normal rights.

This patch updates safesocket to do the aforementioned impersonation,
extract the token handle, and then revert the impersonation. We retain
the token handle for the remaining duration of the connection (the token
continues to be valid even after we have reverted back to self).

Since the token is a property of the connection, I changed ipnauth to wrap
the concrete net.Conn to include the token. I then plumbed that change
through ipnlocal, ipnserver, and localapi as necessary.

I also added a PermitLocalAdmin flag to the localapi Handler which I intend
to use for controlling access to a few new localapi endpoints intended
for configuring auto-update.

clientupdate: distinguish when auto-updates are possible (#9896)
clientupdate.Updater will have a non-nil Update func in a few cases
where it doesn't actually perform an update:
* on Arch-like distros, where it prints instructions on how to update
* on macOS app store version, where it opens the app store page

Add a new clientupdate.Arguments field to cause NewUpdater to fail when
we hit one of these cases. This results in c2n updates being "not
supported" and `tailscale set --auto-update` returning an error.

taildrop: switch hashing to be streaming based (#9861)
While the previous logic was correct, it did not perform well.
Resuming is a dance between the client and server, where
1. the client requests hashes for a partial file,
2. the server then computes those hashes,
3. the client computes hashes locally and compares them.
4. goto 1 while the partial file still has data

While step 2 is running, the client is sitting idle.
While step 3 is running, the server is sitting idle.

By streaming over the block hash immediately after the server
computes it, the client can start checking the hash,
while the server works on the next hash (in a pipelined manner).
This performs dramatically better and also uses less memory
as we don't need to hold a list of hashes, but only need to
handle one hash at a time.

There are two detriments to this approach:
* The HTTP API relies on a JSON stream,
  which is not a standard REST-like pattern.
  However, since we implement both client and server,
  this is fine.
* While the stream is on-going, we hold an open file handle
  on the server side while the file is being hashed.
  On really slow streams, this could hold a file open forever.

taildrop: implement asynchronous file deletion (#9844)
File resumption requires keeping partial files around for some time,
but we must still eventually delete them if never resumed.
Thus, we implement asynchronous file deletion, which could
spawn a background goroutine to delete the files.

We also use the same mechanism for deleting files on Windows,
where a file can't be deleted if there is still an open file handle.
We can enqueue those with the asynchronous file deleter as well.
