Callers that need to turn logtail uploads on and off in response to user preference or policy changes previously had no choice: the package-level Disable is a one-way kill switch intended for the controlplane DisableLogTail debug message, and requires a process restart to undo. Add a per-Logger disabled flag, toggled via SetEnabled, that drops incoming entries without buffering while disabled. The process-wide Disable still takes precedence, so a controlplane-issued kill switch cannot be overridden by a client setting it back on. To simplify https://github.com/tailscale/tailscale-android/pull/695 Updates #13174 Change-Id: I06e75bd719c851f5f837ca5b2d1e17f7c68355f0 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
