ZF-8668: Zend_File_Transfer: Adapter does not extend Zend_File_Transfer_Adapter
When instantiating an instance of Zend_File_Transfer, the following exception is thrown:
Zend_File_Transfer_Exception: Adapter Zend_File_Transfer_Adapter_Http does not extend Zend_File_Transfer_Adapter' in /path/to/Zend/File/Transfer.php on line 56
As of ZF 1.9.6, there is no Zend_File_Transfer_Adapter. Instead, the adapters need to extend Zend_File_Transfer_Adapter_Abstract. The attached patch fixes the condition and exception message to reflect this.
