Volker Lendecke 277eac1a8e lsa4_srv: Factor out dcesrc_lsa_valid_AccountRight()
The previous code in dcesrv_lsa_AddRemoveAccountRights had the following snippet:

if (sec_privilege_id(rights->names[i].string) == SEC_PRIV_INVALID) {
        if (sec_right_bit(rights->names[i].string) == 0) {
                talloc_free(msg);
                return NT_STATUS_NO_SUCH_PRIVILEGE;
        }
        talloc_free(msg);
        return NT_STATUS_NO_SUCH_PRIVILEGE;
}

If I'm not mistaken, the inner if-statement is essentially dead code,
as regardless of the outcome of the if-condition we execute the same
code. The effect of this is that you can't "net rpc rights grant" a right,
for example SeInteractiveLogonRight. A quick test against a W2k12 server
shows that W2k12 allows this call.

This patch changes the semantics of dcesrv_lsa_AddRemoveAccountRights
to also allow "rights" to be granted and revoked. At the same
time, it centralizes the check for validity of user input from
dcesrv_lsa_EnumAccountsWithUserRight into dcesrc_lsa_valid_AccountRight
too.
