mem: Add a generic id field to the packet trace
This patch adds an optional generic 64-bit identifier field to the
packet trace. This can be used to store the sequential number of the
instruction that gave rise to the packet, thread id, master id,
"sub"-master within a larger module etc. As the field is optional it
has a marginal cost if not used.
