Revert part of the last commit, remove {g|s}etflags from the libc

2000-02-05T18:42:36+00:00

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.

Remove unnecessary -g for CFLAGS.

 -g for CFLAGS which was set at debugging time was mistakenly committed,
 so removed it.

Fix ftpd core dump when hostname is not set.

2000-02-03T09:59:36+00:00

  When hostname is not set, ftpd core dumps, because there is no
  NULL check for freeing name resolving information for its own
  hostname.
  So the check is added.

sync iruserok() extension API with other BSDs

2000-02-01T15:55:56+00:00

  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.
