libtracefs: Add a pthread_mutex per instance
Add a pthread_mutex per instance such that modifications being done on
specific instances do not interfere with each other. This also includes a
new "toplevel_lock" that is to be used when modifying the toplevel
instance.
Convert the filter_mutex over to the toplevel/instance locking.
