This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware. Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.

1. After calling sendto(), the packet will be unreferenced.
Call coap_pending_cycle() to make sure the packet is referenced until
we got the response from the peer or retransmission timeout.
2. In retransmit_request(), we rearrange the order to avoid the issue.
3. Remove IPv4 configuration for source code is expecting IPv6
4. Correct a typo in README.rst
5. Initialize the interface w/ IPv6 address
