Top level build now tests Samba3 and Samba4

[Andrew Bartlett]

Just a heads-up, we now build and test all of Samba in 'make test' from
the top level build. 

This includes tests that show Samba3 joins and accepts real time NTLM
and Kerberos logins when joined to Samba4.

Also, we have been making great progress with the overlapping symbol
set:  We also now have only 63 symbols overlapping in bin/smbd in the
top level build.
