This isn't currently supported due to missing support in upstream
dependencies, and also we don't use this package anywhere right now.
Just conditionally skip this for now.

OSS-Fuzz doesn't update their version of Go as quickly as we do, so
we sometimes end up with OSS-Fuzz being unable to build our code for
a few weeks. We don't want CI to be red for that entire time, but
we also don't want to forget to reenable fuzzing when OSS-Fuzz does
start working again.
This change makes two configurations worthy of a CI pass:
- Fuzzing works, and we expected it to work. This is a normal
happy state.
- Fuzzing didn't compile, and we expected it to not compile. This
is the "OSS-Fuzz temporarily broken" state.
If fuzzing is unexpectedly broken, or unexpectedly not broken, that's
a CI failure because we need to either address a fuzz finding, or
update TS_FUZZ_CURRENTLY_BROKEN to reflect the state of OSS-Fuzz.

Github's matrix runner formats the race variant as '(amd64, true)' if we
use race=true. So, change the way the variable is defined so that it says
'(amd64, race)' even if that makes the if statements a bit more complex.

Instead of having a dozen files that contribute CI steps with
inconsistent configs, this one file lists out everything that,
for us, constitutes "a CI run". It also enables the slack
notification webhook to notify us exactly once on a mass breakage,
rather than once for every sub-job that fails.

The use of GOOS to mean "the compiler's host architecture" ends up
overriding whatever GOOS the user passed in, resulting in befuddling
errors like "unsupported GOOS/GOARCH pair linux/wasm" when the caller
requests js/wasm.

We've never used the "[ci skip]" magic commit header in our history,
across all our repos. This seems to be boilerplate we imported years
ago and have since been copying around our CI configs.

With #6566 we added an external mechanism for getting the default
interface, and used it on macOS and iOS (see tailscale/corp#8201).
The goal was to be able to get the default physical interface even when
using an exit node (in which case the routing table would say that the
Tailscale utun* interface is the default).
However, the external mechanism turns out to be unreliable in some
cases, e.g. when multiple cellular interfaces are present/toggled (I
have occasionally gotten my phone into a state where it reports the pdp_ip1
interface as the default, even though it can't actually route traffic).
It was observed that `ifconfig -v` on macOS reports an "effective interface"
for the Tailscale utn* interface, which seems promising. By examining
the ifconfig source code, it turns out that this is done via a
SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears
to have been around for a long time (e.g. it's in the 10.13 xnu release
at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html)
and thus is unlikely to go away.
We can thus use this ioctl if the routing table says that a utun*
interface is the default, and go back to the simpler mechanism that
we had before #6566.

As part of the work on #7248 I wanted to know all of the flags on the
RouteMessage struct that we get back from macOS. Though it doesn't turn
out to be useful (when using an exit node/Tailscale is the default route,
the flags for the physical interface routes are the same), it still seems
useful from a debugging/comprehensiveness perspective.
Adds additional Darwin flags that were output once I enabled this mode.

Followup to #7235, we were not treating the formatting arguments as
variadic. This worked OK for single values, but stopped working when
we started passing multiple values (noticed while trying out #7244).

Commit 59c254579e moved a lot of work
from functions that could be eliminated at compile time (because
tests against runtime.GOOS are compile-time constant), into code
that must always run before main().
So, revert that, and instead optimize the package only by moving the
remaining string processing code behind sync.Onces.

Useful when debugging issues (e.g. to see the full routing table), and
easier to refer to the output via a browser than trying to read it from
the logs generated by `bugreport --diagnose`.
Behind a canDebug() check, similar to the /magicsock and /interfaces
endpoints.

This package is an initial implementation of something that can read
netfilter and iptables rules from the Linux kernel without needing to
shell out to an external utility; it speaks directly to the kernel using
syscalls and parses the data returned.
Currently this is read-only since it only knows how to parse a subset of
the available data.

Having an empty `on` spec results in the job still running, but it
immediately fails with a "No jobs were run" message.

With #6566 we started to more aggressively bind to the default interface
on Darwin. We are seeing some reports of the wrong cellular interface
being chosen on iOS. To help with the investigation, this adds to knobs
to control the behavior changes:
- CapabilityDebugDisableAlternateDefaultRouteInterface disables the
alternate function that we use to get the default interface on macOS
and iOS (implemented in tailscale/corp#8201). We still log what it
would have returned so we can see if it gets things wrong.
- CapabilityDebugDisableBindConnToInterface is a bigger hammer that
disables binding of connections to the default interface altogether.

We don't require any cert at all for Noise-over-plaintext-port-80-HTTP,
so why require a valid cert chain for Noise-over-HTTPS? The reason we use
HTTPS at all is to get through firewalls that allow tcp/443 but not tcp/80,
not because we need the security properties of TLS.

The 255 byte limit was chosen more than 3 years ago (tailscale/corp@929635c9d98642d34ac735e0c2004f6d3d53c706),
when iOS was operating under much more significant memory constraints.
With iOS 15 the network extension has an increased limit, so increasing
it to 4K should be fine.
The motivating factor was that the network interfaces being logged
by linkChange in wgengine/userspace.go were getting truncated, and it
would be useful to know why in some cases we're choosing the pdp_ip1
cell interface instead of the pdp_ip0 one.
