MFC r326276:
various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task.
The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
No functional change intended.

A major overhaul of the CARP implementation. The ip_carp.c was started from scratch, copying needed functionality from the old implemenation on demand, with a thorough review of all code. The main change is that interface layer has been removed from the CARP. Now redundant addresses are configured exactly on the interfaces, they run on.
The CARP configuration itself is, as before, configured and read via SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or SIOCAIFADDR_IN6 may now be configured to a particular virtual host id, which makes the prefix redundant.
ifconfig(8) semantics has been changed too: now one doesn't need to clone carpXX interface, he/she should directly configure a vhid on a Ethernet interface.
To supply vhid data from the kernel to an application the getifaddrs(8) function had been changed to pass ifam_data with each address. [1]
The new implementation definitely closes all PRs related to carp(4) being an interface, and may close several others. It also allows to run a single redundant IP per interface.
Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for idea on using ifam_data and for several rounds of reviewing!

Add CARP (Common Address Redundancy Protocol), which allows multiple hosts to share an IP address, providing high availability and load balancing.
Original work on CARP done by Michael Shalayeff, with many additions by Marco Pfatschbacher and Ryan McBride.
FreeBSD port done solely by Max Laier.
Patch by: mlaier Obtained from: OpenBSD (mickey, mcbride)
