Subject:    * When Alpine is trying to decide which client-id to choose it
 used to limit      its choices the
 ps_global->vars[V_XOAUTH2_INFO].current_val.l. Now it will      also use
 ps_global->vars[V_XOAUTH2_INFO].main_user_val.l. In addition some      of the
 code in alpine/xoauth2conf.c was moved to the c-client library.
