core: Detect bad passphrase error on certificate import

* src/import.c (gpgme_op_import_result): Check fpr for NULL.
(parse_error): New.
(import_status_handler): Handle error status line.

* doc/gpgme.texi (gpgme_import_status_t): Mention that fpr can be NULL.

* tests/gpg/t-import.c (check_result): Check fpr for NULL.
* tests/run-threaded.c (delete_impres): Check fpr for NULL.

When importing an encrypted certificate a wrong passphrase may be
entered. In this case gpgsm emits a status line with a bad passphrase
error and an "invalid object" error. To make it possible for callers
to handle a wrong passphrase error more gracefully, an import status
with bad passphrase error is added to the import result for each
status line with bad passphrase error.
