spdx: initial adoption of licensing ID tags.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

The file machine/ieeefp.h needs sys/cdefs.h on amd64 and i386 after my
compiler features tests. This is ok, since machine/ieeefp.h is an internal
interface. But floatingpoint.h is a public interface and some ports use it,
so include sys/cdefs.h in the amd64 and i386 version of floatingpoint.h.

Note: some architectures don't provide recursive inclusion protection in
floatingpoint.h, namely alpha and ia64. Except for this part and now the
include of sys/cdefs.h, all those files are equal (from a compiler POV),
so they could be moved to only one version in src/include/.

o Move the contents of <machine/floatingpoint.h> over to

o Remove the i386 specific inclusion of <machine/floatingpoint.h>
from <ieeefp.h>, now that including <machine/ieeefp.h> is enough
for all architectures.
o Allow <machine/ieeefp.h> to inline the functions exposed by the
headers by checking for _IEEEFP_INLINED_ in the MI header. When
defined, prototypes are not given and it is assumed that the MD
headers, when inlining only a subset of the functions provide
prototypes for the functions not being inlined.

Boy, I'm glad we're not using sup anymore. This update would have been
