This removes a limitation on the number of port types, simplifies the API, and removes a central point of coordination. * libguile/ports-internal.h (struct scm_t_port_type): Rename from scm_t_ptob_descriptor, now that it's private. Add GOOPS class fields. (struct scm_t_port): Rename from struct scm_port, especially considering that deprecated.h redefines scm_port using the preprocessor :(. * libguile/ports.h: Add definitions of SCM_PORT and SCM_PORT_TYPE, though the scm_t_port and scm_t_port_type types are incomplete. (SCM_TC2PTOBNUM, SCM_PTOBNUM, SCM_PTOBNAME): Remove, as there are no more typecodes for port types. (scm_c_num_port_types, scm_c_port_type_ref, scm_c_port_type_add_x): Remove. (scm_make_port_type): Return a scm_t_port_type*. All methods adapted to take a scm_t_port_type* instead of a ptobnum. (scm_c_make_port_with_encoding, scm_c_make_port): Take a port type pointer instead of a tag. (scm_new_port_table_entry): Remove; not useful. * libguile/ports.c: Remove things related to the port kind table. Adapt uses of SCM_PORT_DESCRIPTOR / scm_t_ptob_descriptor to use SCM_PORT_TYPE and scm_t_port_type. * libguile/deprecated.c: * libguile/deprecated.h: * libguile/filesys.c: * libguile/fports.c: * libguile/fports.h: * libguile/print.c: * libguile/r6rs-ports.c: * libguile/strports.c: * libguile/strports.h: * libguile/tags.h: * libguile/vports.c: * test-suite/standalone/test-scm-c-read.c: Adapt to change. * libguile/goops.c (scm_class_of, make_port_classes) (scm_make_port_classes, create_port_classes): Adapt to store the classes in the ptob.
