[PATCH 1/3] packet: Use flexible array member in struct pool

[David Gibson <david@gibson.dropbear.id.au>]

Currently we have a dummy pkt[1] array, which we alias with an array of
a different size via various macros.  However, we already require C11 which
includes flexible array members, so we can do better.
