s3-netapi Add libnetapi_net_init(), don't double-init common Samba subsystems
The issue here is that libnet and net were both trying to load the smb.conf files, the case tables and set the debug levels. The set of the debug levels caused problems, because it would force the level to 0, not (say) 10 as requested on the command line. This regression was apparently introduced in cf4de8ec2c8df2ceabbe3d836d296b058e7b19fb when eliminating AllowDebugChange. Andrew Bartlett
