5450aa20ea Fix getipnodebyname(3) bug.

748554442d Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

ebbd43d98f Yank out the NOPOLL conditionals. libc_r no longer needs it, and this
library depends on other things that come *way* later than poll() now
(sigset size changes in particular)

d4ba157d9f Don't retry connecting via the same medium.
I changed to close to original code before merging IPv6 support.
It seems having delay before another try is useless.  However, I'm
not sure that delay means.  So, I leave it as-is.

145f71945d Alocate rcmd{,_af}()'s *ahost argument using malloc() (well
strdup()) rather than pointing it at something that's free()d
(via freeaddrinfo(res)) before the function returns.

I appreciate that this is an API change, but it's the only way
(AFAIK) of doing this without breaking existing code that uses
rcmd{,_af}().

63c050d16c Try and fix the worst of some highly bogus malloc/free resource
management involving rcmd_af(), getaddrinfo(), freeaddrinfo(), etc.
We set *ahost to point to ai->canonname; and later free the ai-> stuff
and still leave the old pointers in *ahost to the freed data.
Perhaps the best way to deal with this is a static buffer or a static
strdup() that is freed on the next iteration or something.  This gives
me headaches just thinking about this.

The new 'AJ' default for malloc() tripped this up.
