	* log.c: (vzlog) Take a single va_list argument and use va_copy
	  as necessary for multiple traversals.
	  (zlog) Pass only one va_list to vzlog.
	  (zlog_*,plog_*) Use a macro for boilerplate code; pass only one
	  va_list to vzlog.
	  (zlog_set_file) Remove unused 2nd argument (flags).
	  (zlog_save_cwd,zlog_get_cwd,zlog_free_cwd) Remove unused functions.
	* log.h: Remove ZLOG_*_INDEX defines (no longer used).
	  Remove unused 2nd argument from zlog_set_file prototype.
	  Fix prototype for zlog_rotate.
	* command.c: (config_log_file) Remove unused 2nd arg to zlog_set_file.
	* vty.c: (vty_out) Fix stdarg usage to perform multiple traversals
	  properly.
	  (vty_log) Must use va_copy for multiple traversals of va_list arg.
