As to names, a contrib folder is traditionally for code that is hosted,
but not supported by the project.  ie, contributed modules that have
external maintainers.  Certainly another name could be chosen however. 

As you know, we have quite a bit of external code in the tree, which
maintains it's original licence headers and is not in any one location -
we have lib/popt, source4/heimdal, source4/scripting/samba-external and
buildtools/bin/waf*.  In most cases we have a README explaining the
original source, but we may be missing some.  I would not favour a
wholesale relocation of code to create an artificial line between
'samba-developed' and imported codebases. 

I understand how you read the FSF's website suggesting that we have to
change licence headers of imported code.  However, this has not been our
practice in the past, may be considered rude by the original authors,
(yes, it happens!) would make it harder to clearly contribute that code
back.  As a thought experiment, imagine if we did that to the Heimdal
codebase we also host!
