sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Kernel support for the Vector-Scalar eXtension (VSX) found on the POWER7
and POWER8. This instruction set unifies the 32 64-bit scalar floating
point registers with the 32 128-bit vector registers into a single bank
of 64 128-bit registers. Kernel support mostly amounts to saving and
restoring the wider version of the floating point registers and making
sure that both scalar FP and vector registers are enabled once a VSX
instruction is executed. get_mcontext() and friends currently cannot
see the high bits, which will require a little more work.

As the system compiler (GCC 4.2) does not support VSX, making use of this
from userland requires either newer GCC or clang.

Make single precision floating point arithmetic actually work -- I think
it never did -- and fix an obvious missing line. Floating point emulation
on Book-E still needs some work but this gets it basically functional on
soft-FPU systems (hard FPU for Book-E is not yet implemented).
