Remove trace_read_data() and trace_peek_data()
The trace_read_data and trace_peek_data() required a global file
descriptor for reading. This was kept because the library libparsevent
had the function graph tracer implementation and required a callback
to read. This code has been moved out of parse_events.c and into a
special override function.
Now it still uses the global read, but since libtracecmd has a little more
scope than libparsevent, we added a thread variable
tracecmd_curr_thread_handle
This is unique per thread, and is set right after data is read.
Yes there are some races, but we can deal with it for now.
