snow and socket libraries

Hi, folks:

I'm running STk on Solaris 2.3, and I've found that snow
does not support socket calls. It may not support other
things as well, but sockets are what I'm working on at the
moment. :-)

The reason appears to be that, at least under Solaris, the
networking functions require -lnsl and -lsocket, and the
configure script only uses these flags as part of the X
build (i.e. for building STk). By adding them to the
snow-bin rule in Src/Makefile, snow can be made to support
sockets.

Unfortunately, we don't have an up-to-date copy of Autoconf
locally, so I can't test any changes to configure.in or
Makefile.in. It appears that something like the following
needs to be done:

  * Add these lines to configure.in:

    AC_HAVE_LIBRARY(socket, [NETLIBS="-lsocket"])
    AC_HAVE_LIBRARY(nsl, [NETLIBS="$NETLIBS -lnsl"])

  * Add this line to Makefile.in:

    _at_echo "NETLIBS = @NETLIBS@" >> config.make

  * Add "$(NETLIBS)" to the snow-bin rule in Src/Makefile.in.
