compat names kept in <machine/param.h>. In <sys/socket.h>, pull
in <sys/_types.h> instead of the namespace polluting <machine/param.h>
and completely eliminate __CMSG_ALIGN, replaced by _ALIGN

Since the underlying types of the int_fast types are set by machine/_types.h,
put internal macros in that same file and define the exposed
INT_FAST*_{MIN,MAX} macros from those.

__STRICT_ALIGNMENT is talking about accessing of integer types; it does

Doesn't matter much since C++ ABI used by GCC doesn't mangle variable
names; however technically is required by Section 7.5 of the C++ spec.

This allows MI drivers to implement mmap() routines without having to know
about the pmap_phys_address() implementation and #ifdef obfuscation.

MD code would free resources that couldn't be freed until we were no
longer running in that processor. However, it's is unused on all

- provide proper dtoa locks
- use the real strtof implementation
- add strtold, __hdtoa, __hldtoa
- add %a/%A support
- don't lose precision in printf, don't round to double anymore
- implement extended-precision versions of libc functions: fpclassify,
isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is
fixed
- separate vax versions of strtof, and __hdtoa
- add complex math support. added functions: cacos, casin, catan,
ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp,
clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf,
casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf,
ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf,
cimagf, conjf, cprojf, crealf
- add fdim, fmax, fmin
- add log2. (adapted implementation e_log.c. could be more acruate
& faster, but it's good enough for now)
- remove wrappers & cruft in libm, supposed to work-around mistakes
in SVID, etc.; use ieee versions. fixes issues in python 2.6 for
djm@
- make _digittoint static
- proper definitions for i386, and amd64 in ieee.h
- sh, powerpc don't really have extended-precision
- add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h
for LDBL_*
- merge lead to frac for m{6,8}k, for gdtoa to work properly
- add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa
to use
- add EXT_IMPLICIT_NBIT definition, which indicates implicit
normalization bit
- add regression tests for libc: fpclassify and printf
- arith.h & gd_qnan.h definitions
- update ieee.h: hppa doesn't have quad-precision, hppa64 does
- add missing prototypes to gdtoaimp
- on 64-bit platforms make sure gdtoa doesn't use a long when it
really wants an int
- etc., what i may have forgotten...
- bump libm major, due to removed&changed symbols
- no libc bump, since this is riding on djm's libc major crank from
a day ago

parts of the diff ok kettenis@
this commit does not include:
- man page changes

- math.h shouldn't define FLT_EVAL_METHOD, but float.h should (per
C99). remove from math.h, and add proper definitions in float.h

Right now when mi_switch picks up the same proc, we didn't clear the
flag which would mean that every time we service an AST we would attempt
a context switch. For some architectures, amd64 being probably the
most extreme, that meant attempting to context switch for every
trap and interrupt.
Now we clear_resched explicitly after every context switch, even if it
didn't do anything. Which also allows us to remove some more code
in cpu_switchto (not done yet).

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

needs the few MD definitions they (sometimes) provide; only binutils is
interested in them, but binutils provide their own include files for that
purpose anyway.
