diffs for bind 4.8 resolver to work on 2.10BSD

[Stan Barber]

If you want to run the latest release of the resolver library on your
2.10BSD system, you need to obtain the lastest release from Berkeley
and apply these patches to the include and res directories. It should
not affect the use of these same files on systems other than 2.10BSD
so you can maintain a common source if you like.

I have not (nor will I try) to make the name server itself work.

Instructions: cd to the root of the bind source and run this through patch.
Following that, cd res/named and cp gethostnamadr.c gethnamadr.c. This makes
a copy of the file that 2.10BSD file systems can handle.

You can plug the include stuff directly into the /usr/include directories 
and the res stuff into /usr/src/lib/libc/net. Recompile libc and then
recompile the appropriate utilities.
