bit in a long double. For architectures that don't have such a bit,
LDBL_NBIT is 0. This makes it possible to say `mantissa & ~LDBL_NBIT'
in places that previously used an #ifdef to select the right expression.
The optimizer should dispense with the extra arithmetic when LDBL_NBIT
is 0 anyway.
- Add an XXX comment for the big endian case.

surrounding the undef'ing it. It does not seem necessary to
undef some symbol that is not exist, and gcc does not complain
about whether a symbol is exist before #undef'ing it out.

it type and endian clean and removing of stdio dependency from NLS
functions (catalog files now are processed via mmap())
Also following changes were done (against NetBSD version):
. If mmap() failed, set errno to EINVAL and do not try to munmap() file
Obtained from: NetBSD
. Replace inclusion of sys/param.h to sys/cdefs.h and sys/types.h where
appropriate.
. move _*_init() prototypes to mblocal.h, and remove these prototypes
from .c files
. use _none_init() in __setrunelocale() instead of duplicating code
. move __mb* variables from table.c to none.c allowing us to not to
export _none_*() externs, and appropriately remove them from mblocal.h

introducing the disk formats for _RuneLocale and friends.
The disk formats do not have (useless) pointers and have 32-bit
quantities instead of rune_t and long. (htonl(3) only works
with 32-bit quantities, so there's no loss).
Bootstrap mklocale(1) when necessary. (Bootstrapping from 4.x
would be trivial (verified), but we no longer provide pre-5.3
source upgrades and this is the first commit to actually break
it.)
manpages. They are not very related, so separating them makes it
easier to add meaningful cross-references and extend some of the
descriptions.
- Move the part of math(3) that discusses IEEE 754 to the ieee(3)
manpage.
