336c921146 optimize access to arrays of rank 1 or 2
* libguile/array-handle.c (scm_array_handle_pos_1):
  (scm_array_handle_pos_2): New functions.

* libguile/generalized-arrays.c (scm_c_array_ref_1, scm_c_array_ref_2):
  (scm_c_array_set_1_x, scm_c_array_set_2_x): New functions.
  (scm_i_array_ref, scm_i_array_set_x): New subr bindings for array-ref
  and array-set! that avoid consing for arrays of rank 1 or 2.

* test-suite/tests/arrays.test ("array-set!"): Fix expected exception
  for wrong number of indices.

2a610be594 add generic array implementation facility
* libguile/array-handle.c (scm_i_register_array_implementation):
  (scm_i_array_implementation_for_obj): Add generic array facility,
  which will (in a few commits) detangle the array code.
  (scm_array_get_handle): Use the generic array facility. Note that
  scm_t_array_handle no longer has ref and set function pointers;
  instead it has a pointer to the array implementation. It is unlikely
  that code out there used these functions, however, as the supported
  way was through scm_array_handle_ref/set_x.
  (scm_array_handle_pos): Move this function here from arrays.c.
  (scm_array_handle_element_type): New function, returns a Scheme value
  representing the type of element stored in this array.

* libguile/array-handle.h (scm_t_array_element_type): New enum, for
  generically determining the type of an array.
  (scm_array_handle_rank):
  (scm_array_handle_dims): These are now just #defines.

* libguile/arrays.c:
* libguile/bitvectors.c:
* libguile/bytevectors.c:
* libguile/srfi-4.c:
* libguile/strings.c:
* libguile/vectors.c: Register array implementations for all of these.

* libguile/inline.h: Update for array_handle_ref/set change.
* libguile/deprecated.h: Need to include arrays.h now.

c53c0893a3 parts of unif.[ch] to array-handle.[ch]
* libguile/array-handle.c:
* libguile/array-handle.h: Move some parts of unif.c and unif.h to these
  new files.

* libguile/unif.c:
* libguile/unif.h: Update includers. Since unif.h depends on the array
  handle type, we include array-handle.h, which also means that there
  will be no difference for our callers.

* libguile/init.c: Call scm_init_array_handle, though it does nothing as
  of yet.

* libguile/Makefile.am: Adapt for new files.
