* libguile/vectors.c (scm_is_vector): Deprecate use on weak vectors and
  arrays.
  (scm_is_simple_vector): Deprecate use on weak vectors.

  use on arrays.

fb7dd00169 Deprecate general "uniform-vector" interface
* libguile/uniform.h:
* libguile/uniform.c (scm_is_uniform_vector, scm_uniform_vector_p)
  (scm_c_uniform_vector_length, scm_uniform_vector_length)
  (scm_uniform_vector_element_type, scm_uniform_vector_element_size)
  (scm_c_uniform_vector_ref, scm_uniform_vector_ref):
  (scm_c_uniform_vector_set_x, scm_uniform_vector_set_x):
  (scm_uniform_vector_to_list)
  (scm_uniform_vector_elements, scm_uniform_vector_writable_elements):
  Deprecate.  This interface lacked both generality and specificity.
  The general replacement is array-length, array-ref, and friends on the
  scheme side, or the array handle interface on the C side.  On the
  specific side of things, there are the specific bytevector, srfi-4,
  and bitvector interfaces.

* test-suite/tests/arrays.test:
* test-suite/tests/bitvectors.test:
* test-suite/tests/ports.test:
* test-suite/tests/srfi-4.test: Update to use array interfaces.

* doc/ref/api-foreign.texi (Void Pointers and Byte Access):
* doc/ref/srfi-modules.texi (SRFI-4): Update.

dc65b88d83 Simplify srfi-4 C implementation
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): In the raw element
  accessors (e.g scm_u32vector_writable_elements), only permit
  bytevectors, as the constructors will only make bytevectors.  This
  harmonizes with the Scheme interfaces as well, which expect packed
  bytevectors.
  (scm_make_srfi_4_vector): Knowing that the new value is a bytevector
  with base 0 and inc 1, simplify initialization.

* libguile/sockets.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_htons, scm_htonl, scm_ntohs, scm_ntohl):
  Deprecate.  Bytevectors adequately subsume their functionality.

* doc/ref/posix.texi:
* test-suite/tests/00-socket.test: Update.

  pt->encoding is "ISO-8859-1".

d360671c1c Fix edge case in 'ash'.
* libguile/numbers.c (left_shift_exact_integer): Fix edge case where
  N is -1 and count is SCM_I_FIXNUM_BIT-1 to return the most negative
  fixnum.  Previously this result was returned as a bignum.

* test-suite/tests/numbers.test (ash): Add tests.

088cfb7d76 Improved error checking in bytevector->uint-list and bytevector->sint-list.
Partially fixes <http://bugs.gnu.org/15100>.
Reported by Göran Weinholt <goran@weinholt.se>.

* libguile/bytevectors.c (INTEGERS_TO_LIST): Make sure SIZE isn't 0.
  Allow SIZE to be greater than the bytevector length, for consistency
  with allowing extra bytes at the end when the bytevector length is
  non-zero.  Use scm_from_size_t instead of scm_from_uint.

* test-suite/tests/bytevectors.test: Add tests.  Remove a test that
  checks for an exception when SIZE is greater than the bytevector
  length.

6f82b8f623 Fix inappropriate uses of scm_syserror in numbers.c.
* libguile/numbers.c (mem2ureal, left_shift_exact_integer,
  floor_right_shift_exact_integer, round_right_shift_exact_integer):
  Use 'assert' instead of 'scm_syserror' to indicate a case that should
  never happen.
