9f0ec10fc9 Implement 'string-utf8-length' and 'scm_c_string_utf8_length'.
* libguile/strings.c (utf8_length, scm_c_string_utf8_length)
  (scm_string_utf8_length): New functions.
* libguile/strings.h (scm_c_string_utf8_length, scm_string_utf8_length):
  New prototypes.
* doc/ref/api-data.texi (Bytevectors as Strings): Add docs.
* doc/ref/guile.texi: Update manual copyright date to 2015.

79072a210a Struct and array GDB pretty printers hint as arrays
* libguile/libguile-2.0-gdb.scm (make-scm-pretty-printer-worker):
  (%scm-pretty-printer): Refactor to avoid printing all struct / array
  fields by hinting these as arrays.  The resulting print is not as
  faithful to the original data, but that's probably OK.

649ec8d823 Accessor methods only apply to subclasses with their slot
* libguile/goops.c (is_accessor_method, scm_compute_applicable_methods):
  Fix regression from 51f66c9120 (2009).
  Accessor methods are added on each subclass on which the slot is
  present; therefore if a subclass doesn't have a method, then the
  methods doesn't apply.  Truly fixes #17355, unlike
  583a23bf10.

* module/oop/goops.scm (compute-cmethod, compute-getter-method)
  (compute-setter-method): Revert earlier changes.

* test-suite/tests/goops.test ("accessor slots"): Update for new
  expectations, in agreement with Guile 1.8.

ed72201a79 Fix buffer overrun with unbuffered custom binary input ports.
Fixes <http://bugs.gnu.org/19621>.

Before that, in 'cbip_fill_input', BUFFERED would be set to 0 when
reading from 'scm_getc' et al, because 'shortbuf' was being used.  Thus,
we could eventually execute this line:

      /* Copy the data back to the internal buffer.  */
      memcpy ((char *) c_port->read_pos, SCM_BYTEVECTOR_CONTENTS (bv),
	      c_octets);

But 'read_pos' would quickly point to the fields beyond 'shortbuf',
thereby leading to a corruption of the 'scm_t_port' itself.

* libguile/r6rs-ports.c (cbip_setvbuf): When READ_SIZE is 0, keep using
  BV as the 'read_buf'.
  (cbip_fill_input): Adjust assertion to accept 'read_buf_size = 1'.
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
  input port unbuffered & 'get-string-all'", "custom binary input port
  unbuffered UTF-8 & 'get-string-all'"]: New tests.
