v29.0 - 2022-09-06:
Tracing service and probes:
* Add support for only tracing selected syscalls. By selecting only syscalls
of interest, usage of the trace buffer and performance impact on device
is reduced.
* Add support for parsing DSI ftrace events.
Trace Processor:
* Make calling NotifyEndOfFile more than once an error: this was deprecated
in v28. Flush should be used instead for all by the final call.
* Add parsing and ingestion for V4L2 events.
* Upgraded SQLite to 3.39.2.
UI:
* Add support for searching Android log events.
* Group kernel wakelock tracks into a single track group.
SDK:
* Added support for startup tracing. Tracing can be started in an app
before it connects to the tracing service.
The data sources which are started for startup tracing, will
be automatically adopted to normal tracing session once we start
normal tracing session.
* Added the |first_packet_on_sequence| boolean which is set the first packet
emitted on each TraceWriter.
