riastradh | math.h: Add math_errhandling, MATH_ERRNO, MATH_ERREXCEPT.
XXX Should maybe put a __math_errhandling in machine/math.h, but only
VAX uses MATH_ERRNO and that's not likely to change any time soon, so
this will serve for now with less churn.

riastradh | math.h: Define FP_FAST_FMA, FP_FAST_FMAF, FP_FAST_FMAL.
These are not strictly necessary to define, really, so we haven't
exactly been nonconformant. But they tell programs when they can
enable fast paths by using the fma(3) family of functions.

math.h: Move declarations under appropriate namespace tests.
Not sure about _REENTRANT, but if gamma_r and lgamma_r go under that
(even if _NETBSD_SOURCE isn't defined), then lgammal_r probably
should too.

kre | It seems that we need prototypes for long double math functions, even
when !__HAVE_LONG_DOUBLE -- they still exist, but just aren't...
This might unbreak several more builds.

kre | This set of changes seem to be sufficient to make at least the
amd64 port build again after the long double math function infusion
from yesterday.
Feel free (without consulting me, I'm just hacking about) to revert
any of this and do it a better way.
Note: this is not intended to be complete, in particular, in <math.h>
I added prototypes only for the functions that are needed for a
successful build, not all of the new ones...

-get cabs() and cabsf() out of public view - these are historical and
conflict with C99 functions which are builtins in newer gcc
(actually, the old cabs() is ABI compatible with the new _complex one
on i386, but this is purely accidental)

subdirectory as libc does so that binary compatibility is kept

bjh21 | Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

simonb | Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
