260ba0bff1 lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

bc1685ae93 Replace SOFTFLOAT with __mips_soft_float, which gcc/clang define for us.
D8376 extended softfloat/hardfloat support, but used a macro that never
actually gets set except in libc and msun's Makefile.inc.  So libc and libm
got built correctly, but any program including fenv.h itself assumed it was
on a hardfloat systen and emitted inline fpu instructions for
fedisableexcept() and friends.

Using __mips_soft_float makes everything work in all cases, since it's a
compiler-internal macro that is always set correctly for the target

e15001607c libm: remove duplicate version script entries
These symbols already appear in the common lib/msun/Symbol.map.
Duplicate entries produce an error with LLVM's LLD linker.

fbeb8fc5ac Add full softfloat and hardfloat support for MIPS.
This adds new target architectures for hardfloat:
mipselhf mipshf mips64elhf mips64hf.

Tested in QEMU only.

1e6760c16a Use #include "fenv.h" instead of #include <fenv.h>. This makes it
more convenient to compile the math library by itself.

a38603b0b5 Provide external definitions of all of the standardized functions in
fenv.h that are currently inlined.

The definitions are provided in fenv.c via 'extern inline'
declaractions.  This assumes the compiler handles 'extern inline' as
specified in C99, which has been true under FreeBSD since 8.0.

The goal is to eventually remove the 'static' keyword from the inline
definitions in fenv.h, so that non-inlined references all wind up
pointing to the same external definition like they're supposed to.
I am deferring the second step to provide a window where
newly-compiled apps will still link against old math libraries.
(This isn't supported, but there's no need to cause undue breakage.)
