23d961a13f . Static'ize functions exported via function reference variables only. 
. 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

dff27cebe2 Make the format of LC_CTYPE files architecture independent by 
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.)

  implementations of sgetrune() and sputrune() in terms of
  mbrtowc() and wcrtomb().
- Rename the old rune-wrapper mbrtowc() and wcrtomb() functions to
  __emulated_mbrtowc() and __emulated_wcrtomb().
- Add __mbrtowc and __wcrtomb function pointers, which point to the
  current locale's conversion functions, or the __emulated versions.
- Implement mbrtowc() and wcrtomb() as calls to these function pointers.
- Make the "NONE" encoding implement mbrtowc() and wcrtomb() directly.
