(dump_read, dump_write): Add macros for these flags. * filter.c (filter_types): Add fd filter type. * filter.h (DECL_FILTER): Add fd filter declaration. (DECL_FILTER_ACTION): Add read and write filter action declarations. * filter_action.c (action_types): Add read and write filter action types. * filter_qualify.c (read_set, write_set): Remove set variables. (qualify_read, qualify_write): Use new filtering API. * number_set.h (read_set, write_set): Remove set variable declarations. * syscall.c (dumpio): Check dump_read, dump_write macros instead of global sets.
