Michael Tuexen 86eda749af Cleanup the handling of error causes for ERROR chunks. This fixes 
an inconsistency of the padding handling. The final padding is
now considered to be a chunk padding.

* Blocking I/O is enabled on any TCP type socket by default. For the UDP
* model if this is turned on then the socket buffer is shared for send
* resources amongst all associations. The default for the UDP model is that
* is SS_NBIO is set. Which means all associations have a separate send
* limit BUT they will NOT ever BLOCK instead you will get an error back
* EAGAIN if you try to send too much. If you want the blocking semantics you
* set this option at the cost of sharing one socket send buffer size amongst
* all associations. Peeled off sockets turn this option off and block. But
* since both TCP and peeled off sockets have only one assoc per socket this
* is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
* model OR peeled off UDP model, but we do allow you to do so. You just use
* the normal syscall to toggle SS_NBIO the way you want.
*
* Blocking I/O is controlled by the SS_NBIO flag on the socket state so_state
