Jon Shallow 756bb04239 pdu building: Enforce the application order of building a PDU ...

Make coap_add_option() invalid after calling a coap_add_data*() function.
Add in internal support for adding options to PDUs that contain data with
a replacement coap_add_option_internal() function.  Call this new function
in the appropriate places in the libcoap src.

Add coap_log warnings when the application tries to build a PDU in the wrong
order and then return failure.

Update documentation re-inforcing the PDU building order.
