tools lib traceevent: Implement new traceevent APIs for accessing struct tep_handler fields
As struct tep_handler definition is not exposed as part of libtraceevent
API, its fields cannot be accessed directly by the library users. This
patch implements new APIs, which can be used to access the struct
tep_handler fields:
tep_get_event() - retrieves an event pointer at a specific index
tep_get_first_event() - is modified to use tep_get_event()
tep_clear_flag() - clears a tep handle flag
tep_test_flag() - test if a given flag is set
tep_get_header_timestamp_size() - returns the size of the timestamp stored
in the header.
tep_get_cpus() - returns the number of CPUs
tep_is_old_format() - returns true if data was created by an
older kernel with the old data format
tep_set_print_raw() - have the output print in the raw format
tep_set_test_filters() - debugging utility for testing tep filters
