Makefile: Added files to smbpasswd.c.
loadparm.c: Patch from tim@quiknet.com for static string problems. server.c: Setup global_myname. smbpass.c: Fix up locking. Add machine_password_delete() call. smbpasswd.c: Added provisional code to add to a domain. lib/rpc/client/cli_login.c: Fixed incorrect cred_hash3 call when setting machine password. lib/rpc/server/srv_netlog.c: Fixed incorrect cred_hash3 call when setting machine password. Jeremy. (This used to be commit 6a7164233e3bf9d6bb57c44a53204068e454ae5c)
