the lock is held by other thread, but not when nobody owns it. According
to deischen@, this part of code will never be hit in our threads
library, since it does not use locks without wait/wakeup functions.

undef some symbol that is not exist, and gcc does not complain
about whether a symbol is exist before #undef'ing it out.

Also following changes were done (against NetBSD version):

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.)
inputs. The trouble with replacing two floats with a double is that
the latter has 6 extra bits of precision, which actually hurts
accuracy in many cases. All of the constants are optimal when float
arithmetic is used, and would need to be recomputed to do this right.

ia64 (pluto1), i386+SSE (Pentium 4), and sparc64 (panther), and a
negligible improvement for i386 without SSE. (The i386 port still
uses the hardware instruction, though.)

formats that incorrectly make large requests (ZIP did this until
recently) or with block sizes over 32k.
