add a BPF_RND load location that provides a random value. this will be used so a bpf filter can make a decision based on a random number, which in turn will be used so a filter can perform random sampling of packets rather than capturing all packets. random sampling means that we don't have to figure out how to make bpf coordinate multiple concurrent calls to do counter based sampling. BPF_RND is currently backed with arc4random. discussed with many including jmatthew@, alex wilson, claudio@, sthen@, deraadt@, and tb@ ok kn@ tb@ jmatthew@ i call this extended bpf... xBPF.

refactor bpf_filter a bit. the code was confusing around how it dealt with packets in mbufs vs plain memory buffers with a lenght. this renames bpf_filter to _bpf_filter, and changes it so the packet memory is referred to by an opaque pointer, and callers have to provide a set of operations to extra values from that opaque pointer. bpf_filter is now provided as a wrapper around _bpf_filter. it provides a set of operators that work on a straight buffer with a lenght. this also adds a bpf_mfilter function which takes an mbuf instead of a buffer, and it provides explicit operations for extracting values from mbufs. if we want to use bpf filters against other data structures (usb or scsi packets maybe?) we are able to provide functions for extracting payloads from them and use _bpf_filter as is. ok canacar@
