add "sample NUM" so you can ask to capture 1/NUM packets from a filter.
the use of the sample keyword matches similar config in other
products.
NUM can be a number between 2 and 1048576, and is used to divide
0x100000000 into a threshold that is then compared against a randomly
generated number produced by a load of BPF_RND.
having sampling as part of the grammar means you can write things
like "icmp or sample 128". this lets you capture all icmp traffic
and a sample of the rest of the traffic.
