ZF-5945: Zend_Validate_Barcode_Ean13 and Zend_Validate_Barcode_UpcA error messages should handle differents keys

Description

Errors keys shouldn't be "invalid" or "invalidLengh" and shouldn't be the same fo ZVB_Ean13 and AVB_UpcA as it causes translations issues when using both components and having a global translation array for a form.

Comments

Duplication of ZF-3920 and ZF-3164

Issue was postponed until 2.0 after a discussion with the dev-team. Reason is that the fix for this issue would be a BC break.

Probably fixed with r17874 for ZF 1.10
