The counter can be used to track failures on parsing event format files. It is updated automatically by tep_parse_event(), when failure is detected. The patch also adds two new APIs for accessing the counter: tep_get_parsing_failures() - returns the current value of the counter. tep_clear_parsing_failures() - clears the counter.

This makes the struct consistent with the chosen naming convention: tep (trace event parser), instead of the old pevent.

A library function should not force the application to exit. In the current implementation tep_filter_add_filter_str() calls exit() when a special "test_filters" mode is set, used only for debugging purposes. When this mode is set and a filter is added - its string is printed to the console and exit() is called. This patch changes the logic - when in "test_filters" mode, the filter string is still printed, but the exit() is not called. It is up to the application to track when "test_filters" mode is set and to call exit, if needed.
