Mihai Parparita 62f4df3257 net/interfaces, net/netns: add node attributes to control default interface getting and binding
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.

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Brad Fitzpatrick ba5aa2c486 version, cmd/tailscale: add version.Meta, tailscale version --json
Add `tailscale version --json` JSON output mode. This will be used
later for a double-opt-in (per node consent like Tailscale SSH +
control config) to let admins do remote upgrades via `tailscale
update` via a c2n call, which would then need to verify the
cmd/tailscale found on disk for running tailscale update corresponds
to the running tailscaled, refusing if anything looks amiss.

Plus JSON output modes are just nice to have, rather than parsing
unstable/fragile/obscure text formats.

Tom DNetto f1ab11e961 ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths
Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With
this change:

 - Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded)
   require either the WIP envknob or CapabilityTailnetLockAlpha.
 - Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the
   envknob / capability.
 - Auxillary commands (ie: changing tka keys) require TKA to be initialized.

The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being
sent the capability or setting the envknob on tailscaled yourself.

I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock().

Brad Fitzpatrick fb4e23506f control/controlclient: stop restarting map polls on health change
At some point we started restarting map polls on health change, but we
don't remember why. Maybe it was a desperate workaround for something.
I'm not sure it ever worked.

Rather than have a haunted graveyard, remove it.

In its place, though, and somewhat as a safety backup, send those
updates over the HTTP/2 noise channel if we have one open. Then if
there was a reason that a map poll restart would help we could do it
server-side. But mostly we can gather error stats and show
machine-level health info for debugging.
