Fix gethostbyaddr() prototype to conform to IEEE Std 1003.1:
http://www.opengroup.org/onlinepubs/009695399/functions/gethostbyaddr.html
gethostbyaddr_r() is changed as well. It breaks ABI backward compatibility on 64 bit arch. So, we fix it on 32 bit arch only for now.

Update the resolver in libc to BIND9's one.
Since, res_sendsigned(3) and the friends use MD5 functions, it is hard to include them without having MD5 functions in libc. So, res_sendsigned(3) is not merged into libc.
Since, res_update(3) in BIND9 is not binary compatible with our res_update(3), res_update(3) is leaved as is, except some necessary modifications. The res_update(3) and the friends are not essential part of the resolver. They are not defined in resolv.h but defined in res_update.h separately in BIND9. Further, they are not called from our tree. So, I hide them from our resolv.h, but leave them only for binary backward compatibility (perhaps, no one calls them).
Since, struct __res_state_ext is not exposed in BIND9, I hide it from our resolv.h. And, global variable _res_ext is removed. It breaks binary backward compatibility. But, since it is not used from outside of our libc, I think it is safe.

Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror) that this provokes. "Wherever possible" means "In the kernel OR NOT C++" (implying C).
There are places where (void *) pointers are not valid, such as for function pointers, but in the special case of (void *)0, agreement settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many of the fixes were NULL where ascii <nul> ('\0') was needed, and a few were just "other".

Make the resolver(3) and many associated interfaces much more reentrant. The getaddrinfo(3), getipnodebyname(3) and resolver(3) can coincide now with what should be totally reentrant, and h_errno values will now be preserved correctly, but this does not affect interfaces such as gethostbyname(3) which are still mostly non-reentrant.
In all of these relevant functions, the thread-safety has been pushed down as far as it seems possible right now. This means that operations that are selected via nsdispatch(3) (i.e. files, yp, dns) are protected still under global locks that getaddrinfo(3) defines, but where possible the locking is greatly reduced. The most noticeable improvement is that multiple DNS lookups can now be run at the same time, and this shows major improvement in performance of DNS-lookup threaded programs, and solves the "Mozilla tab serialization" problem.
No single-threaded applications need to be recompiled. Multi-threaded applications that reference "_res" to change resolver(3) options will need to be recompiled, and ones which reference "h_errno" will also if they desire the correct h_errno values. If the applications already understood that _res and h_errno were not thread-safe and had their own locking, they will see no performance improvement but will not actually break in any way.
Please note that when NSS modules are used, or when nsdispatch(3) defaults to adding any lookups of its own to the individual libc _nsdispatch() calls, those MUST be reentrant as well.

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.

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.
