Add "-L" flags to LDFLAGS, not LIBS, and get rid of all the exotic
searching that tries to figure out in what directory libpcap lives - we
should treat "-L" just like "-I", rather than adding a ton of
complication to do it the way the autoconf maintainers think, for some
reason, it should be done (by adding "-L" flags to LIBS - "-L" flags
don't specify libraries, so I have no clue why they think they belong in
LIBS; they specify a search path for libraries, just as "-I" flags
specify a search path for header files, so they strike me as "flags to
the linker" rather than "libraries", and LDFLAGS, unlike LIBS, appears
before *all* "-l" flags, including those specified by PCAP_LIBS and so
on).

For "pcap_findalldevs()", don't assume that just because it's in -lpcap
it's usable - one of the updates to OS X 10.3 updated libpcap to
0.8[.x], so that it had "pcap_findalldevs()", but didn't update
"pcap.h", so it didn't declare "pcap_if_t", so you couldn't actually
*use* it. You can work around that by installing the pcap.h (and
pcap-bpf.h) from the matching tcpdump.org release, but, as even when
that version of OS X is pre-installed rather than being the result of a
Software Update, you still don't get the new "pcap.h" (at least I didn't
get it on my PowerBook with 10.3.4). Therefore, we check whether a
program that calls "pcap_findalldevs()" *and* declares a "pcap_if_t *"
to pass to it can be compiled and linked with -lpcap, and only declare
HAVE_PCAP_FINDALLDEVS if we can.
Also, don't check for the functions added to libpcap after
"pcap_findalldevs()" was added unless we have a usable
"pcap_findalldevs()", as, if not, those functions won't be declared in
"pcap.h" either, so we'll get compiler warnings.

# use the native zlib rather than building and installing
# the crappy old version that comes with XFree86.)
