Add libnl-3 detection to configure
Switch from version to attribute for libnl
Compile pcap by attributes not lib versions Add libnl3 include dir
Merge branch 'master' of git://github.com/dragorn/libpcap

Changes from dragorn to Handle libnl3.
Regenerate configuration file.

(What button was I supposed to push to mark dragorn as the author of the
previous changes?  And why do they default to a not-very-interesting
"Merged from blahblahblah" message?  Is the expectation that you'll edit
it to indicate what the merged changes actually do?)
Note Mike Kershaw's fixes to handle libnl3.
