Error codes and error handling

Macros
#define	QDB_ERROR_ORIGIN(x)   ((x) & (int)0xF0000000)
	Extracts the origin out of a qdb_error_t.
#define	QDB_ERROR_SEVERITY(x)   ((x) & (int)0x0F000000)
	Extracts the severity out of a qdb_error_t.
#define	QDB_SUCCESS(x)   (((x) == qdb_e_ok) || (QDB_ERROR_SEVERITY(x) == qdb_e_severity_info))
	True if and only if the qdb_error_t indicates a success.
#define	QDB_FAILURE(x)   (!QDB_SUCCESS(x))
	True if and only if the qdb_error_t indicates a failure.

Typedefs
typedef enum qdb_error_origin_t	qdb_error_origin_t
