Packet generator: preserve pcap file timestamps
Set vnet_buffer2(b0)->pg_replay_timestamp, for use when desired. Fix a memory leak in pg_stream_free(...), which wasn't freeing the replay packet templates. Change-Id: I01822a9e91a52de4774d2b95cf0c2ee254a915e9 Signed-off-by: Dave Barach <dave@barachs.net>
