Add --with-libnl autoconfig parameter and dependency
between libpcap and libnl1.

Disable libnl1 by default to avoid libpcap build error
when libnl1 is involved.

These patches where tweaking both configure.in and configure, which is
bad since configure changes after an autoconf. If the patch is re-applied
for some reason it would notice that it's already appiled and fails.

do_configure was using relative paths in do_configure with the assumption that
$S is the same as $B.  This isn't always true, so explicitly use $S.

libpcap notices libusb in its configure if its sysrooted
and ignores it if its not. But this causes problems since
there is no explicit dependency on libusb. Rebuild from shared
state sometimes fails when libusb has not been yet populated
in sysroot and libpcap has. And do_configure of consumers of libpcap e.g. tcpdump
are probing for features on libpcap. All the tests fail since
none of link steps succeed and it sees as if libpcap does
not have required features and configure of tcpdump bails out.

turn canusb into PACKAGECONFIG and let it be disabled
by default.

Backport additional patches needed for disable-canusb to work

libpcap uses libnl on Linux to support sniffing mac80211 devices, which could be
useful.
