- Do not require the packet structure of the header have the same
lifetime as the underlying bytes or the parsed representation.
- Add the bytes of the contained options to the parsed representation
structure.
- Add the IPv6OptionsIterator structure to make iterating over the
contained options easier.

This optimization makes sure that enqueueing to an empty ring buffer
would never wrap around, in turn ensuring that enqueueing to an empty
packet buffer would never use more than one metadata entry.
Right now, pushing buffer-sized packets into a packet buffer requires
at least two metadata entries, which is surprising and wasteful.
Implement a simple way to discover and respond to three duplicate ACKs
from the reciver of the data. This leads to a fast retransmit of the
last unacknowledged seqment. This is feature is described in [RFC 5681].

Add the FailureType enumeration that can be acquired from a IPv6
extension header option which determines the required action if the
extension header option type is not known or is not supported.

Ensure that cargo does not attempt to autodiscover examples. This causes
problems with utils.rs and ensures that an example section exists in the
Cargo.toml.
Only ACKs generated by `dispatch` were updating
`remote_last_win` but not the ACKs generated by
`process`, failing to keep track of the last
announced receive window. This left
`window_to_update` to return false in `dispatch`
after the RX buffer was emptied, thus not announcing
that the receive window is not zero anymore.
The change updates `remote_last_win` for immediate
ACKs generated by `process`.

Each given NDISC packet type may only include one of a few options.
Instead of including the options in the NDISC repr as a &[u8] include
the packet types available options as `Option<T>`.

- Add a function to EthernetInterface useful for determining if a
received packet with the source address being a solicited node
address is the solicited node address for an IPv6 address assigned
to the interface.
- Add SOLICITED_NODES_PREFIX to Ipv6Cidr
- Fix some nits
