tools lib traceevent: Introduced new traceevent API, for adding new plugins directories.
Implement new traceevent plugin API, which can be used to add new plugins
directories:
enum tep_plugin_load_priority {
TEP_PLUGIN_FIRST,
TEP_PLUGIN_LAST,
};
int tep_add_plugin_path(struct tep_handle *tep, char *path,
enum tep_plugin_load_priority prio);
It adds the "path" as new plugin directory, in the context of the
handler "tep". The tep_load_plugins() API searches for plugins in this
new location. Depending of the priority "prio", the plugins from this
directory are loaded before (TEP_PLUGIN_FIRST) or after
(TEP_PLUGIN_LAST) the ordinary libtraceevent plugin locations.
