This commit adds a `replicas` field to the `Connector` custom resource that
allows users to specify the number of desired replicas deployed for their
connectors.
This allows users to deploy exit nodes, subnet routers and app connectors
in a highly available fashion.

This will start including the sytray app in unstable builds for Linux,
unless the `ts_omit_systray` build flag is specified.
If we decide not to include it in the v1.88 release, we can pull it
back out or restrict it to unstable builds.

In Android, we are prompting the user to select a Taildrop directory when they first receive a Taildrop: we block writes on Taildrop dir selection. This means that we cannot use Dir inside managerOptions, since the http request would not get the new Taildrop extension. This PR removes, in the Android case, the reliance on m.opts.Dir, and instead has FileOps hold the correct directory.
This expands FileOps to be the Taildrop interface for all file system operations.

If a conn.Close call raced conn.ReadFromUDPAddrPort before it could
"register" itself as an active read, the conn.ReadFromUDPAddrPort would
never return.
This commit replaces all the activeRead and breakActiveReads machinery
with a channel. These constructs were only depended upon by
SetReadDeadline, and SetReadDeadline was unused.

In the components where an event bus is already plumbed through, remove the
exceptions that allow it to be omitted, and update all the tests that relied on
those workarounds execute properly.
This change applies only to the places where we're already using the bus; it
does not enforce the existence of a bus in other components (yet),

jsonv2 now returns an error when you marshal or unmarshal a time.Duration
without an explicit format flag. This is an intentional, temporary choice until
the default [time.Duration] representation is decided (see golang/go#71631).
setting.Snapshot can hold time.Duration values inside a map[string]any,
so the jsonv2 update breaks marshaling. In this PR, we start using
a custom marshaler until that decision is made or golang/go#71664
lets us specify the format explicitly.
This fixes `tailscale syspolicy list` failing when KeyExpirationNotice
or any other time.Duration policy setting is configured.

Ideally when we attempt to create a new port mapping, we should not return
without error when no mapping is available. We already log these cases as
unexpected, so this change is just to avoiding panicking dispatch on the
invalid result in those cases. We still separately need to fix the underlying
control flow.

This occasionally panics waiting on a nil ctx, but was missed in the
previous PR because it's quite a rare flake as it needs to progress to a
specific point in the parser.

When kubectl starts an interactive attach session, it sends 2 resize
messages in quick succession. It seems that particularly in HTTP mode,
we often receive both of these WebSocket frames from the underlying
connection in a single read. However, our parser currently assumes 0-1
frames per read, and leaves the second frame in the read buffer until
the next read from the underlying connection. It doesn't take long after
that before we end up failing to skip a control message as we normally
should, and then we parse a control message as though it will have a
stream ID (part of the Kubernetes protocol) and error out.
Instead, we should keep parsing frames from the read buffer for as long
as we're able to parse complete frames, so this commit refactors the
messages parsing logic into a loop based on the contents of the read
buffer being non-empty.
k/k staging/src/k8s.io/kubectl/pkg/cmd/attach/attach.go for full
details of the resize messages.
There are at least a couple more multiple-frame read edge cases we
should handle, but this commit is very conservatively fixing a single
observed issue to make it a low-risk candidate for cherry picking.
