RE: [Mip4] Additional 3344bis error codes

["Chowdhury, Kuntal" <kchowdhury at starentnetworks.com>]

Henrik,

How about the following error codes:

- MN-HA Auth failure
- MN-AAA Auth failure
- MN-AAA Authentication timed out with AAA

(Note: currently "MN Auth failure" is sent as a generic error code for
all the above)

- Dynamic Home address is not available (IP Pool exhausted)
- Static home address not available 
- Require reverse-tunnel for private home address
- Improper ordering of extensions (Note: currently "poorly formed
request" is overloaded for this)
