Now that we're using rand.Shuffle in a few locations, create a generic
shuffle function and use it instead. While we're at it, move the
interleaveSlices function to the same package for use.

The debug flag on tailscaled isn't available in the macOS App Store
build, since we don't have a tailscaled binary; move it to the
'tailscale debug' CLI that is available on all platforms instead,
accessed over LocalAPI.

Followup to #7177 to avoid adding extra dependencies to the CLI. We
instead declare an interface for the link monitor.

WSL has started to set the eth0 default route interface default to 1280
MTU, which is too low to carry 1280 byte packets from tailscale0 once
wrapped in WireGuard. The change down to 1280 is very likely smaller
than necessary for almost all users. We can not easily determine the
ideal MTU, but if all the preconditions match, we raise the MTU to 1360,
which is just enough for Tailscale traffic to work.

This is to address a possible DNS failure on startup. Before this
change IPv6 addresses would be listed first, and the client dialer would
fail for hosts without IPv6 connectivity.
This ensures that we're trying multiple returned IPs, since the DERP
servers return the same response to all queries. This should increase
the chances that we eventually reach a working IP.

By default, cmd/dist only prints the output of failed commands.
With this, you can turn all the noisy output back on.

Signed-off-by: David Anderson <danderson@tailscale.com>
The helper suppresses output if the command runs successfully. If the
command fails, it dumps the buffered output to stdout before returning
the error. This means the happy path isn't swamped by debug noise or
xcode being intensely verbose about what kind of day it's having,
but you still get debug output when something goes wrong.

Given recent changes in corp, I originally thought we could remove all of the
syso files, but then I realized that we still need them so that binaries built
purely from OSS (without going through corp) will still receive a manifest.
We can remove the arm32 one though, since we don't support 32-bit ARM on Windows.

Uses the hooks added by tailscale/go#45 to instrument the reads and
writes on the major code paths that do network I/O in the client. The
convention is to use "<package>.<type>:<label>" as the annotation for
the responsible code path.
Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).
For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.
We also keep track of the current interface so that we can break out
the stats by interface.

Exposes the delegated interface data added by #7248 in the debug
endpoint. I would have found it useful when working on that PR, and
it may be handy in the future as well.
Also makes the interfaces table slightly easier to parse by adding
borders to it. To make then nicer-looking, the CSP was relaxed to allow
inline styles.

Github requires explicitly listing every single job within a workflow

This makes gocross and its bootstrap script understand an absolute

Signed-off-by: David Anderson <danderson@tailscale.com>
We need to build gocross from multiple repos, but Go's innate
git hash embedding only works when you build gocross from this repo,
not when you build it from elsewhere via 'go build
tailscale.com/tool/gocross'. Instead, explicitly embed the version
found with 'git rev-parse HEAD', which will work from any git repo.
