startup writers: Commit locally buffered data in batches If a lot of data is buffered in the StartupTraceWriters, we may end up stalling during binding because we fill up the SMB with the buffered data in a quick burst. This patch makes it possible to commit the locally buffered data into the SMB in smaller batches, waiting for the service to process each batch before committing the next. The underlying TraceWriter may commit future chunks at any time after the first batch of buffered data chunks is committed (i.e. while other batches are pending asynchronous commit). This is not an issue because the service can handle chunks being committed out-of-order. Bug: 136235443 Change-Id: Ic9e2d2e085ca2b14758867a7060d179171de9d2b
