combined s3/s4 build - initial build working

[Stefan (metze) Metzmacher]

Hi Tridge,

> binaries are functional. We haven't tested all functionality, but the
> basics work (eg. bin/smbd, bin/nmbd, bin/samba, authentication etc).

> You then configure and build in the top level directory, and you will

> For binaries that have common names, the tree currently adds a '3'

Thanks your work on that:-)

I've just build the current version of your toplevel-wip branch,
it's nice that the s3build/ directory isn't needed anymore.

But I'd like to that we make sure that the s3 binaries only link in
the needed stuff.

Currently smbd links against libgensec.so.0, libldb.so.1,
libsamba-util.so.0,
libsamba-sockets.so, libcredentials.so, libsamdb.so.0 and a few others,
which should
not be needed.

Please let me review the final branch before you push to master.
