bitvector-bit-set? / bitvector-bit-clear? replace bitvector-ref
This is an opportunity to make a new interface that can be more
efficient in 3.0 (because no generic array support), easier to read (no
need for 'not'), and more consistent with other bitvector interfaces.
* NEWS: Add entry.
* doc/ref/api-data.texi (Bit Vectors): Update.
* libguile/array-handle.h (bitvector_ref, scm_array_get_handle): Adapt
to bitvector changes.
* libguile/bitvectors.h:
* libguile/bitvectors.c (scm_c_bitvector_bit_is_set)
(scm_c_bitvector_bit_is_clear): New functions.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_bitvector_ref): Deprecate.
* module/ice-9/sandbox.scm (bitvector-bindings): Replace
bitvector-ref with bitvector-bit-set? / bitvector-bit-clear?.
* module/system/vm/disassembler.scm (instruction-has-fallthrough): Use
bitvector-bit-clear?.
* test-suite/tests/bitvectors.test: Update.
