Subject: [PATCH] OTHER: _xmmsv_dict_hash: make hash function
 endianness-agnostic

The following code:
    uint32_t k;
    memcpy (&k, data, sizeof (k));
computes different data depending on platform endianness.

That causes test_xmmsv_serialize_coll_match test to fail
as collection order is serialized in wrong order.
