[RELEASE] ltt-control 0.85, lighter page cache use

I just released ltt-control 0.85 which waits for previous subbuffers to be
written to disk (using sync_file_range()) and uses fadvise to tell the kernel
that pages won't be reaccessed. This lessens the tracer impact on the page

Thanks to Linus for hints on how to use fadvise and sync_file_range to do
this, c.f.:
