[0/6] New libtracefs APIs

Message

Tzvetomir Stoyanov (VMware) Jan. 7, 2021, 8:32 a.m. UTC

Added new APIs to tracefs library and updated man pages and unit tests:
  tracefs_instance_file_read_int();
  tracefs_instance_file_open();
  tracefs_trace_is_on();
  tracefs_trace_on();
  tracefs_trace_off();
  tracefs_trace_on_fd();
  tracefs_trace_off_fd();

The main motivation is to cover trace-cmd use cases of tracefs library.
These APIs are the first step in that direction.
