Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

David Anderson 55b1221db2 net/packet: support full IPv6 decoding.
The packet filter still rejects all IPv6, but decodes enough from v6
packets to do something smarter in a followup.
