Import a number of core functions from libpcap-1.2.0 while preserving

local changes: strncpy() -> strlcpy(), malloc(x * y) -> calloc(x, y),
exclude cross-platform cruft, etc.

The new functions are pcap_create(), pcap_set_snaplen(),
pcap_set_promisc(), pcap_can_set_rfmon(), pcap_set_rfmon(),
pcap_set_timeout(), pcap_set_buffer_size(), pcap_activate(), and
pcap_statustostr().

This diff was tested on amd64, i386, macppc, and sparc64, where
regression tests were done on various pcap-based ports (especially amd64
and i386 where regression tests were run on all pcap-based ports).
Testers also tried running pcap-based ports that they are familiar with
to ensure that there is no behavioral change.  tcpdump and pflogd in
base were also tested by different testers.  The new pcap_* functions
were tested with a proof-of-concept Snort 2.9 port for many months.

Thank you to everyone who helped test this diff and provided feedback:

Aaron Bieber, Markus Lude, and Ray Percival.
