dd: avoid buffer allocations unless needed

* src/dd.c: Add new static global variable ibuf.
(alloc_ibuf, alloc_obuf): New functions factored from dd_copy().
(dd_copy): Call the new functions to allocate memory for
ibuf and obuf when necessary.
(skip): Likewise.
* tests/dd/no-allocate.sh: New test.
* tests/local.mk: Reference the test.
