native/net/tapdev: Fix for new `UIP_CONF_IPV6` handling.
Added `*.orig`, `*~`, and `.DS_Store` to `.gitignore`.
Use memcpy, memcmp functions for the rime compare and copy functions as they
are already used all over contiki.
Code style fixes
Fixes imposibility of receiving data when a node not using RPL joins a network
which does.

The RPL header is processed, declared invalid and the packet discarded. This
is fixed by this commit.
Limit size of uip/tcpip stack when not using TCP at all.
Make DS6 route notifications optional.

[examples] Remove broken example with no clear purpose

This example didn't compile, had no actual code changes in the last ~6
years, had no documentation explaining it's purpose, and insufficient
code comments to provide a useful example.  Removing it in favour of
fewer, but clearer, examples, that are easier to keep maintained.
