248aee623c 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.

686d0736aa Fix coredump in gethostbyaddr() when the returned answer is too large to
fit in the static buffer.  This fix causes it to look like there is no
 data available, which is also wrong but is better than dumping core.

c8d2fd6da8 Update libc dns code to 4.9.7-T1B level. This involved chopping out large
chunks of res_comp.c and replacing it with chunks of bind-8.1.1's resolver
code.  (There are no interface changes though)
The other parts are better bounds checking related.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

64cf8d66e2 Disable isxdigit block until proper solution will be found
isxdigit(name[0]) gives false failures on short names which looks
like hexadecimal digits, f.e. "fade", "babe", "d133", etc.

ca785773f6 Here goes.. Bring the 4.9.5-P1 resolver into -current. This has the
DNSSEC stuff, among other things.  There are also some renamed functions,
I've left out the res_stubs.c from this commit in case cvs bombs out..

3951b8e32c Small yet significant tweaks/cleanups:
- getservent:
  o put _yp_check() proto under #ifdef YP where it belongs
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- gethostbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long

- getnetbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- ether_addr:
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
    but it happens that BUFSIZ == YPMAXRECORD.

- gethostbydns:
  o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)

These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.

6b73680dcf Make the __dns_getanswer() wrapper work right. For the newer versions
of BIND, we need to tweak some things to that gethostanswer() knows
whether or not we're dealing with an IPv4 or IPv6 address. (This'll
teach me to use a 2.1.0 system for NIS development -- but it's so nice
and stable I just can't being myself to upgrade it. :)

e5ad4f8712 Update the resolver part of libc to bind-4.9.3-beta24 level (from beta9p1)
Note that this was done by selective patching from diffs, to not conflict
with the 4.4bsd base code..  This was *not* a trivial task..  I have been
testing this code (apart from cosmetic changes) in my libc for a while now.

40569757cc In _gethostbydnsaddr(), force RES_RECURSE into _res.options. This is
incredibly obnoxious, but also makes inverse mappings work when the local
resolver is in a cache-only configuration.  (Maybe this is actually
a bug in BIND?)
