Previously were always setting `UseSocketOnly` because we were
comparing `args.socketpath != ""`, but `args.socketpath` flag
always gets filled with `paths.DefaultTailscaledSocket()` when
not provided. Rather than comparing to the empty string, compare
to the default value to determine if `UseSocketOnly` should be
set.
Should fix issue with web client being unreachable for Mac App

This PR changes the internal getTokenInfo function to use generics.
I also removed our own implementations for obtaining a token's user
and primary group in favour of calling the ones now available in
x/sys/windows.
Furthermore, I added two new functions for working with tokens, logon
session IDs, and Terminal Services / RDP session IDs.
I modified our privilege enabling code to allow enabling of multiple
privileges via one single function call.
Finally, I added the ProcessImageName function and updated the code in
tailscaled_windows.go to use that instead of directly calling the
underlying API.
All of these changes will be utilized by subsequent PRs pertaining to
this issue.

In corp PR #14970 I updated the installer to set a security mitigation that
always forces system32 to the front of the Windows dynamic linker's search
path.
Unfortunately there are other products out there that, partying like it's
1995, drop their own, older version of wintun.dll into system32. Since we
look there first, we end up loading that old version.
We can fix this by preloading wintun using a fully-qualified path. When
wintun-go then loads wintun, the dynamic linker will hand it the module
that was previously loaded by us.

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.

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.

We no longer build Windows releases with cgo enabled, which
automatically turned off certstore support. Rather than re-enabling cgo,
we updated our fork of the certstore package to no longer require cgo.
This updates the package, cleans up how the feature is configured, and
removes the cgo build tag requirement.

Instead of just falling back to making a TCP query to an upstream DNS
server when the UDP query returns a truncated query, also start a TCP
query in parallel with the UDP query after a given race timeout. This
ensures that if the upstream DNS server does not reply over UDP (or if
the response packet is blocked, or there's an error), we can still make
queries if the server replies to TCP queries.
This also adds a new package, util/race, to contain the logic required for
racing two different functions and returning the first non-error answer.

on macOS at least.
To repro, add this to tstest/integration:
func TestFailInFewSeconds(t *testing.T) {
t.Parallel()
time.Sleep(3 * time.Second)
os.Exit(1)
t.Fatal("boom")
}
Those three seconds let the other parallel tests (with all their
tailscaled child processes) start up and start running their tests,
but then we violently os.Exit(1) the test driver and all the children
were kept alive (and were spinning away, using all available CPU in
gvisor scheduler code, which is a separate scary issue)
