Add wrappers for target->type->examined:

- replace all checks of target->type->examined with target_was_examined().
- replace all setting of target->type->examined with target_set_examined().
- replace clearing of target->type->examined with target_reset_examined().
- add documentation in target_s to warn not to access field directly.
