f6b767e33f Add two additional references to the See Also section, which contain much 
better descriptions of UTF-8 and related issues.

a019c0e525 Remove unnecessary inclusion of <rune.h> to make it obvious that this file 
does not use the deprecated rune system.

c5929b304e Handle boundary cases more correctly; mblen(s, 0) and mbtowc(NULL, s, 0) 
return -1 regardless of what s points to, mbtowc(&w, s, 1) sets w to a
null wide character when s points to a null byte. This seems to be closer
to what most other implementations do, but the C99 standard contradicts
itself for these cases.

972baa3747 Add a UTF-8 encoding method, which will eventually replace the antique 
"UTF2" method. Although UTF-8 and the old UTF2 encoding are compatible
for 16-bit characters, the new UTF-8 implementation is much more strict
about rejecting malformed input and also handles the full 31 bit range
of characters.

f4da1a754d Add support for the 6 new C99 struct lconv members dealing with formatting 
international monetary values: int_p_cs_precedes, int_n_cs_precedes,
int_p_sep_by_space, int_n_sep_by_space, int_p_sign_posn, int_n_sign_posn.
This should not break existing binaries or LC_MONETARY data files.

are based on tolower(3) and toupper(3) instead of the old towlower(3).

9981ef2702 Point out that although toupper() and tolower() really accept rune_t's 
and not just unsigned char's, callers should use towupper() and towlower()
instead when working with wide characters if portability is a concern.

o Change all occurrences of NTOHL() and associated marcros in the
  source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
  Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.
