transform: Discard previously-received packets

Keep a bitmap of previously-received packets (by sequence number
offset) and discard duplicates.

This feature can only be enabled if the bitmap (32 bits) is big enough
for the sequence number window (`max-skew'), but this is true by
default, and the feature is enabled by default when available.
