 	* many files: Update applications to add an exit status variable, make priority jumping optional, and use new args parsing macros
 	* pbx.c cdr.c res/res_features.c apps/app_dial.c include/asterisk/cdr.h: Convert some built-in applications to use new args parsing macros.  Change ast_cdr_reset to take a pointer to an ast_flags structure instead of an integer for flags.
