Jon Shallow c9f40d7d09 request-tag: Add in support for sending Request-Tag option with every request ...

If multiple requests (apart from DELETE) are sent at the same time to
the same resource, and the responses need to make use of the Block2 option,
there is no way for the server to differentiate between which block set a
request (if there is a resource content change) is for unless a Request-Tag
is used.

Disable this functionality by setting COAP_BLOCK_NO_PREEMPTIVE_RTAG when
calling coap_context_set_block_mode().  Request-Tag will still be sent
with any request that includes Block1 option.
