* libguile/ephemerons.h: * libguile/ephemerons.c (scm_c_ephemeron_load, scm_c_ephemeron_push): New routines. * libguile/ioext.c (scm_fdes_to_ports): Rework in terms of scm_c_port_for_each. * libguile/ports-internal.h (struct scm_t_port): Add pointer to entry on weak ports list, so that we can cancel it easily. * libguile/ports.c (release_port): Mark weak ports list entry as dead. (all_ports_needing_close, for_each_port_needing_close): Rework as ephemeron chain. (scm_c_make_port_with_encoding, close_port, scm_c_port_for_each): Adapt API. (scm_init_ports): No more weak set.
