Update CoAP to 4.0.11 

This PR implement https://tools.ietf.org/html/rfc7959#section-2.5
"The error code 4.13 (Request Entity Too Large) can be returned at any
time by a server that does not currently have the resources to store
blocks for a block-wise request payload transfer that it would intend
to implement in an atomic fashion. (Note that a 4.13 response to a
request that does not employ Block1 is a hint for the client to try
sending Block1, and a 4.13 response with a smaller SZX in its Block1
Option than requested is a hint to try a smaller SZX.)
