Subject: pack-write: use hashwrite_be32() instead of double-buffering array
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hashwrite() already buffers writes, so pass the fanout table entries
individually via hashwrite_be32(), which also does the endianess
conversion for us.  This avoids a memory copy, shortens the code and
reduces the number of magic numbers.
