Remove 'contiguous' flag in arrays

Browse source 
Was never used, so we save having to set it on various ops.

* libguile/arrays.h (SCM_I_ARRAY_FLAG_CONTIGUOUS,
  SCM_SET_ARRAY_CONTIGUOUS_FLAG, SCM_CLR_ARRAY_CONTIGUOUS_FLAG,
  SCM_I_ARRAY_CONTP): Remove.
* libguile/arrays.c (scm_i_ra_set_contp): Remove. Elsewhere remove all
  uses of this and the other macros.

@ -19,6 +19,11 @@ Use scm_is_vector instead.
If you were including these headers directly for any reason, just include libguile.h instead.
** scm_from_contiguous_typed_array has been removed.
This function was undocumented. Instead, use scm_make_typed_array and
the array handle functions to copy data to the new array.
* Backward incompatible changes
