carray-replace: two overrun bugs.
* ffi.c (carray_replace): In the case when we replace a larger
range by a smaller one, when the upper part of the aray shifts
down, we are not correctly clearing to zeros the vacated part
of the array. The variable whole is a displacement from the
base of the array, not from ptr. Secondly, the copying loop
must go rom fr to below sn, not below vn; sn is derived from
vn but truncated not to go past the array.
* tests/017/carray.tl: New file. Several cases here fail
before this fix.
