e94c6cb4a2 . 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

1949a3470f Implement the GNU extensions of mbsnrtowcs() and wcsnrtombs(). These are
convenient when the source string isn't null-terminated.

Implement the other conversion functions (mbstowcs(), mbsrtowcs(), wcstombs(),
wcsrtombs()) in terms of these new functions.

ea4ac135ff Allow encoding modules to override the default implementations of
mbsrtowcs() and wcsrtombs(). Provide a fast implementation for the
trivial "NONE" encoding.

2051a8f2d5 Move prototypes of various encoding-related functions into a new header
file to avoid extern'ing them all over the place.

ca2dae426e Allow partial multibyte characters to accumulate in conversion state
objects passed to mbrtowc(), mbsrtowcs(), and mbrlen(), as required
by C99.

d4f6cd06dd Allow mbrtowc() and wcrtomb() to be implemented directly, instead of
as wrappers around the deprecated 4.4BSD rune functions. This paves the
way for state-dependent encodings, which the rune API does not support.
- Add __emulated_sgetrune() and __emulated_sputrune(), which are
  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.

All of this emulation mess will be removed, together with rune support,
in FreeBSD 6.

9acd2d9b3c Avoid truncating invalid wide characters that are outside the range of
'unsigned char'; signal an error instead.

333fc21e3c Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

d201fe46e3 Remove _THREAD_SAFE and make libc thread-safe by default by
adding (weak definitions to) stubs for some of the pthread
functions.  If the threads library is linked in, the real
pthread functions will pulled in.

Use the following convention for system calls wrapped by the
threads library:
	__sys_foo - actual system call
	_foo - weak definition to __sys_foo
	foo - weak definition to __sys_foo

Change all libc uses of system calls wrapped by the threads
library from foo to _foo.  In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde).  All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes.  <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h  namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.

Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE.  We have recursive mutexes, but would like to avoid
using them if possible.

Remove uneeded includes of <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.

696cbd5ff2 As above.
Oh I also put in a couple of compile-time warnings for the crypt stuff.
