Gregory Nutt 04c9079954 Back in 2007, an early network implementation was developed for NuttX. This early development was inspired largely by uIP 1.0 and recognition of that was noted in the then BSD license headers. Over the next 14 years, a new, much more advanced, original network was developed for NuttX. However, some references to Adam Dunkels were still present in the file headers.
Because of this, it will take some time to detangle the licensing under net/.  Many new features, original features were added to the NuttX network.  Clearly, any references to Adam Dunkels in the files that implement these new features that have no counterpart in uIP 1.0 are errors.

This PR removes the references and converts the license headers to Apache 2.0 where possible.  The affected files include only (1) the implementation of IPv6 (including neighbor support under ICMPv6) and (2) Raw sockets.  Neither of these features are present in uIP 1.0 and the licenses can be freely updated.

* Name: neighbor_findentry
*
* Description:
* Find an entry in the Neighbor Table. This interface is internal to
* the neighbor implementation; Consider using neighbor_lookup() instead;
*
* Input Parameters:
* ipaddr - The IPv6 address to use in the lookup;
*
* Returned Value:
* The Neighbor Table entry corresponding to the IPv6 address; NULL is
* returned if there is no matching entry in the Neighbor Table.
