r16044: Create a samba3 specific file in torture/rpc. The tests in there survive

r16044: Create a samba3 specific file in torture/rpc. The tests in there survive
against W2k3, but they are designed to walk existing Samba3 code paths. It
might be possible that I add something like that to other subdirs like raw/.

RPC-BINDSAMBA3 excercises the bind variants that samba3 supports right now.

RPC-NETLOGSAMBA3 does a samba3 style join, does some schannel-protected
netlogon operations and leaves again. Samba3 right now does not survive this,
I'm about to fix it soon. I'll also post a *VERY* dirty hack (fake users in
sys_getpwnam()) to be able to run this in the build farm.
