Jon Shallow 9f1418e87d coap_block.c: Handle Block1 packets with random order block numbers ...

Add in new COAP_BLOCK_NOT_RANDOM_BLOCK1 option for
coap_context_set_block_mode(). This disables receipt of any Block1
packet (but not Q-BLock1) if the block numbers are not sequentially
received starting with 0.  A 4.08 code is returned for every packet
out of order and its data is ignored.

If COAP_BLOCK_SINGLE_BODY is set in coap_context_set_block_mode(),
but not COAP_BLOCK_NOT_RANDOM_BLOCK1, then all Block1 packets are
assembled in the correct order before passing the body up to the
application.  The receive logic will timeout after MAX_TRANSMIT_WAIT
(93 seconds) if there are any missing blocks, or 10 seconds if the
last block is seen.

If COAP_BLOCK_SINGLE_BODY is not set in coap_context_set_block_mode(),
and not COAP_BLOCK_NOT_RANDOM_BLOCK1, then the random order packets
are passed up to the application layer where it is the application's
responsibility to decide what to do with the randomly ordered packets,
and what response code to send.
