8dcb56dc78 Provide more POSIX-complaint ttyname_r(3) interface[1], which is slightly
different from what has been offered in libc_r (the one spotted in the
original PR which is found in libthr has already been removed by David's
commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h):
	- Use POSIX standard prototype for ttyname_r, which is,
		int ttyname_r(int, char *, size_t);
	  Instead of:
	  	char *ttyname_r(int, char *, size_t);
	  This is to conform IEEE Std 1003.1, 2004 Edition [1].
	- Since we need to use standard errno for return code, include
	  errno.h in ttyname.c
	- Update ttyname(3) implementation according to reflect the API
	  change.
	- Document new ttyname_r(3) behavior
	- Since we already make use of a thread local storage for
	  ttyname(3), remove the BUGS section.
	- Remove conflicting ttyname_r related declarations found in libc_r.

Hopefully this change should not have changed the API/ABI, as the ttyname_r
symbol was never introduced before the last unistd.h change which happens a
couple of days before.

12eb46c8bb Change the definition of NULL on ia64 (for LP64 compilations) from
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
   by virtue of the generated code implicitly widens ints to longs and
   allows the use of an 32-bit integral type for 64-bit arguments.
   Subsequent arguments are passed onto the memory stack, which does
   not exhibit the same behaviour and consequently do not allow this.
   In practice this means that variadic functions taking pointers
   and given NULL (without cast) work as long as the NULL is passed
   in one of the first 8 arguments. A SIGSEGV is more likely the
   result if such would be done for stack-based arguments. This is
   due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
   exception of ia64, allow 32-bit integral types (specifically NULL)
   when 64-bit pointers are expected in variadic functions by way of
   how the compiler generates code. As such, code that works correctly
   (whether rightfully so or not) on any platform other than ia64, may
   fail on ia64.

To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.

This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...

98d1592458 Change brk's prototype from char *brk(const char *) to int brk(const void *)
and sbrk's prototype from char *sbrk(int) to void *sbrk(intptr_t).

This makes us more consistant with NetBSD and standards which include
these functions. Bruce pointed out that ptrdiff_t would probably
have been better than intptr_t, but this doesn't match other
implimentations.

Also remove local declarations of sbrk and unnecessary casting.

418d67b0d9 Revert part of the last commit, remove {g|s}etflags from the libc
interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.

Additionally there were complications with the build/install-world
process.  It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.

There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).

It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

e3be4d7b7e sync iruserok() extension API with other BSDs
Some of rcmd related function is need to be updated to
  support IPv6. Some of them are already updated as standard
  document. But there is also several de-facto functions and
  they are not listed in standard documents.
  They are,

    iruserok()  (used by rlogind, rshd)
    ruserok()   (used by kerberos, etc)

  KAME package updated those functions in original way.

    iruserok_af()
    ruserok_af()

  But recently there was discussion on IETF IPng mailing
  list about how to sync those API, and it is decided,

    -Those function is not standard and not documented.
    -But let BSDs sync their API as de-facto.

  And after some discussion, it is announced that

    -add update to iruserok() as iruserok_sa()
    -no ruserok() API change(it is only updated internaly)

So I sync those API before 4.0 is released.
The changes are,
   -prototype changes
   -ruserok() internal update (use iruserok_sa() inside)
   -removal of ruserok_af()
   -change iruserok_af() as static functioin, and also prefix the name with __.
   -add iruserok_sa() (Just call __iruserok_af() inside)
   -adding flag AI_ALL to getipnodebyaddr() called from __icheckhost().
    This is necessary to support IPv4 communication via AF_INET6 socket
    could be correctly authenticated via iruserok_sa()
   -irusreok_af() call is replaced to iruserok_sa() call
    in rlogind, and rshd.

18c0eeddf7 Historically file flags (schg, uschg, etc) have been converted from
string to u_long and back using two functions, flags_to_string and
string_to_flags, which co-existed with 'ls'.  As time has progressed
more and more other tools have used these private functions to
manipulate the file flags.

Recently I moved these functions from /usr/src/bin/ls to libutil,
but after some discussion with bde it's been decided that they
really ought to go in libc.

There are two already existing libc functions for manipulating file
modes:  setmode and getmode.  In keeping with these flags_to_string
has been renamed getflags and string_to_flags to setflags.

The manual page could probably be improved upon ;)
