5e53a4f90f 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.

e7d939bda2 Remove ia64.
This includes:
o   All directories named *ia64*
o   All files named *ia64*
o   All ia64-specific code guarded by __ia64__
o   All ia64-specific makefile logic
o   Mention of ia64 in comments and documentation

This excludes:
o   Everything under contrib/
o   Everything under crypto/
o   sys/xen/interface
o   sys/sys/elf_common.h

5d9fefacf2 Use #include "fenv.h" instead of #include <fenv.h>. This makes it
more convenient to compile the math library by itself.

d78e594bc9 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.)

10b01832c3 Replace fegetmask() and fesetmask() with feenableexcept(),
fedisableexcept(), and fegetexcept().  These two sets of routines
provide the same functionality.  I implemented the former as an
undocumented internal interface to make the regression test easier to
write.  However, fe(enable|disable|get)except() is already part of
glibc, and I would like to avoid gratuitous differences.  The only
major flaw in the glibc API is that there's no good way to report
errors on processors that don't support all the unmasked exceptions.

f365db00e5 Mark all inline asms that read the floating-point control or status
registers as volatile.  Instructions that *wrote* to FP state were
already marked volatile, but apparently gcc has license to move
non-volatile asms past volatile asms.  This broke amd64's feupdateenv
at -O2 due to a WAR conflict between fnstsw and fldenv there.
