Perfetto v42.0

v42.0 - 2024-02-02:
  Tracing service and probes:
    * Linux/Android: kernel scheduling data (sched_switch and sched_waking
      ftrace events) is now serialised in a more compact format by default
      (previously required setting ftrace_config.compact_sched.enabled).
  UI:
    * Added "Realtime (Trace TZ)" timestamp formatting option to see timestamps
      in the local time of the traced device. It requires recent versions of the
      tracing service which set the system_info.timezone_off_mins field.
    * Added tab support to the plugin API.
    * Added a plugin to improve visualization of Android power traces containing
      ODPM (on-device power rail monitor) data.
    * Added support to attach the UI via ?rpc_port=1234 to multiple instances of
      trace_processor --httpd --http-port=1234 (see UI docs).
    * Fixed OOM detection message on in-memory tables.
    * Fixed rendering of events at the every beginning and end of the trace.
    * Fixed rendering of low density slices.
    * Fixed bug in filterVisibleSlices (Thanks to Liangliang Sui).
  SDK:
    * Fixed a bug that would cause DataSource::OnStop to be called twice upon
      service disconnection with HandleStopAsynchronously().
    * Fixed a long standing bug that caused the last TracePacket for every
      sequence to be lost during scraping, for data sources that do not support
      flushing. The fix works with old versions of the tracing service.
