Use heap-allocated port types instead of ptobnums

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/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.
