#1434 pyosaf: Add wrapped functions with automatic retries and exceptions for raw SAF functions

[Johan Mårtensson]

The SAF functions need to be called in a retry loop to handle timeouts properly. This is done inconsistently in the higher level Python bindings (pyosaf/utils). They also return errors as ints while the code in pyosaf/utils changes this to throw exceptions.

This should be handled consistently by decorating the raw functions with retry logic and raising of exceptions on failure.
