6bf7ec0c9c Thread-safety fixes for iconv and ports
* libguile/ports-internal.h (scm_t_port): Rework to store iconv
  descriptors inline, so that the port finalizer doesn't race with the
  iconv descriptor finalizer.  Access is serialized through a lock.

  could try to free the iconv descriptors at the same time as the
  descriptor finalizer.

  (scm_c_make_port_with_encoding): Initialize iconv-related fields.
  (scm_close_port): Lock while frobbing iconv descriptors.

  while preparing iconv descriptors.

  scm_i_port_iconv_descriptors.
  (scm_port_decode_char): Lock around iconv operations.
  (port_clear_stream_start_for_bom_write): Acquire iconv descriptors
  before checking precise_encoding, to make sure precise_encoding is
  initialized.
* libguile/print.c (display_string_using_iconv): Adapt to use the new
  interface to get iconv descriptors from a port.

7d7e4bc6c0 Fix getsockopt/setsockopt handling of SO_SNDBUF/SO_RCVBUF options.
Reported by Park SungMin <byulparan_eng@icloud.com>
in <https://lists.gnu.org/archive/html/guile-user/2015-11/msg00026.html>.

* libguile/socket.c (scm_getsockopt, scm_setsockopt): Remove code that
  incorrectly assumed that the argument for SO_SNDBUF and SO_RCVBUF
  options was of type 'size_t'.  Both the Linux and POSIX documentation
  indicates that the argument is of type 'int', as is the case for most
  options.

e5d2f4e566 Make scm_t_port private
* libguile/ports-internal.h (enum scm_port_encoding_mode): Remove unused
  enum.
  (scm_t_port_internal, scm_t_port): Make encoding and
  conversion_strategy private. Instead of scm_t_port_internal containing
  scm_t_port, now that all members are private, we can store the user's
  "stream" in a word in the port object itself and make the whole of
  scm_t_port private.  The next commit will remove scm_t_port_internal.
  (SCM_PTAB_ENTRY, SCM_PORT_DESCRIPTOR): Make private.
* libguile/ports.c (scm_c_make_port_with_encoding): Adapt to new port
  layout.
  (scm_port_print): Use SCM_PTAB_ENTRY when printing.
* libguile/ports.h: Remove scm_t_port definition.
* libguile/ioext.c (get_matching_port): Simplify.
* libguile/fports.c (scm_i_evict_port): Simplify.

  line_number, and column_number here.
  (SCM_FILENAME, SCM_SET_FILENAME, SCM_LINUM, SCM_COL, SCM_INCLINE):
  (SCM_ZEROCOL, SCM_INCCOL, SCM_DECCOL, SCM_TABCOL): Make internal.
* libguile/ports.c (scm_c_make_port_with_encoding)
  (scm_set_port_line_x, scm_set_port_column_x): Adapt to change.

209d50c7d8 Embed scm_t_port in scm_t_port_internal
* libguile/ports-internal.h (scm_t_port_internal)
* libguile/ports.h (scm_t_port): Embed scm_t_port in scm_t_port_internal
  so that we have just one allocation.
* libguile/ports-internal.h (SCM_PORT_GET_INTERNAL): Adapt.
* libguile/ports.c (scm_i_port_property, scm_i_set_port_property_x)
  (scm_c_make_port_with_encoding): Adapt.

6ff542ee71 Add random_access_p port type method
* doc/ref/api-io.texi (I/O Extensions): Update documentation on
  implementing port types.  Document get_natural_buffer_sizes.  Document
  the new random_access_p.
* libguile/fports.c (scm_i_fdes_to_port, fport_random_access_p):
  (scm_make_fptob): Instead of frobbing rw_random manually, implement a
  random_access_p function.
