Implement zero-copy bpf(4) buffer or "zbuf" support for libpcap. A slightly
different version has been committed upstream in the libpcap vendor branch.
This will allow people to experiment with zero-copy bpf(4) without requiring
external patches.
Note to enable this functionality:
sysctl net.bpf.zerocopy_enable=1
By default, libpcap will use the legacy buffering method unless this sysctl
variable is set to 1.
For the details about zero-copy bpf(4) implementation see svn change r177548.
