A few final tracefs library fixes and improvements, before releasing it as an official library. v4 changes: - Added new patch: "Use tracefs_list_free() API". - Hid the library non API functions. - When creating a new trace instance, inherit the permissions of the parent "instance" directory. v3 changes: - Addressed Steven's comments. v2 changes: - Change tracefs_instance_create() to return pointer to allocated trace instance structure. - Add new API: tracefs_instance_is_new() to check if the trace instance is newly created by the library.
