usr.sbin/uhsoctl: correct SIOCDIFADDR calls to use ifreq

The SIOCDIFADDR ioctl takes an ifreq structure object, not an ifaliasreq
structure object, as its argument.

The ifreq structure does not include a separate mask field and the
SIOCDIFADDR ioctl handler does not require a network mask as opposed to
the ifaliasreq structure and the SIOCAIFADDR ioctl. Given that
SIOCAIFADDR and SIOCDIFADDR ioctls significantly differ and use
different structures for ioctl arguments, remove ifaddr_add() and move
its logic handling these ioctls to ifaddr_add()'s callers.

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.
