Re-import the v3-3 version of str_list_make().
The merged version behaves differently: "Domain Users" is parsed into two values, as it does not look at quotes. Samba3 users depend on the ability do say for example valid users = "domain users" which would not work anymore with the merged version. Thanks to Björn Jacke for testing this! Volker
