* 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.
