[lttng-dev] [PATCH lttng-tools] Fix: Live tracing does not honor live timer after first tracefile with tracefile rotation

[Mathieu Desnoyers]

When we pass to the 2nd sub-file (or following sub-files) of a stream in
relayd, the live timer has no visible effect from a live reader
perspective, and then everything is flushed when we reach the following
sub-file.

This is caused by the reset of stream->total_index_received after each
tracefile rotation. It should keep on incrementing to match what is
expected by check in check_index_status():

  (rstream->total_index_received <= vstream->last_sent_index)

Fixes #863
