avoid shadowing globals, for WARNS=2

minor constification, good for WARNS=3 now

-const pcap_strerror() for consistency
gencode.c:
date: 2006/04/26 09:24:33; author: tron; state: Exp;
Add missing "const" keywords to match declarations in "pcap.h".

add a volatile variable to prevent vfork/longjmp clobbering.
optimize.c:
date: 2006/05/17 17:48:36; author: drochner; state: Exp;
Make the optimizer use unsigned numbers as the kernel does.
While it is not agreed on that purely unsigned arithmetics is nice,
different behaviour of optimized and unoptimized code is less desirable.

pull in from NetBSD's libpcap: use cloning bpf device on NetBSD
Have the configure script check for paths.h, so that we can include it
only if we have it, and use the cloning BPF device only if we're on
NetBSD *and* _PATH_BPF is defined (hopefully this will keep us from
using it on versions of NetBSD that don't have a cloning BPF device; if,
in the future, other OSes with BPF get cloning BPF devices, we can make
this work for them as well).
Linux. The USB sniffing code for Linux now supplies a per-packet header
based on the one supplied by the Linux binary sniffing interface, so we
add a new DLT_ value and use that.
Fix his e-mail address, and add him to the credits.
If the DAG API supports asking a card for the set of ERF types
it supports, use that capability, to handle cards that support
multiple ERF types. This is to support channelised/fractional
T1/E1.
Don't set the snapshot length - some DAG cards support multiple
capture streams, but the snapshot length is global, so it'd
affect other captures.
Update README.dag.
and if including it declares ether_hostton(), and define
HAVE_DECL_ETHER_HOSTTON appropriately, and use that to determine whether
to define it ourselves, rather than having a set of OSes that don't need
it, as that set can change over time.
Make the default declaration of "ether_hostton()" declare its first
argument as "const char *", as that's what it's *supposed* to be
(although it's not declared as such in some OSes, so we still have to
cast a "const char *" when passed as the first argument).
UN*Xy-enough platform that the Makefile.in rules to generate "version.h"
work), and use the stuff from "version.h" iff HAVE_VERSION_H is defined,
so we can use it even with WinPcap.
supplying a non-stub version of "pcap_findalldevs()", as a list of
devices won't do any good for a capture program.
Don't bother checking for "ifaddrs.h" unless we have "getifaddrs()" -
and if we have "getifaddrs()" but don't have a usable "ifaddrs.h",
report an error, rather than leaving the error for the compile stage.
"snprintf()", include one in libpcap with the name "pcap_snprintf()", so
applications don't have to supply their own "snprintf()" on those
platforms in order to use libpcap.
source files, rather than having a pile of #ifdefs in "inet.c". Add
code to the configure script to determine which implementation to use on
the platform for which libpcap is being built.
Add a "pcap_findalldevs()" implementation for Solaris 8 and later that
handles IPv6 addresses.
return a structure pointer. Check whether the C compiler can handle
inline functions that return a structure pointer, not whether they can
handle inline functions that return an int, as at least some versions of
autoconf's AC_C_INLINE do.
"getifaddrs()"), after processing the list returned by SIOCGIFCONF, scan
"/proc/net/dev" for interface names, and add to the list of interfaces
entries for those interfaces, with no associated addresses (if the
interfaces were already added, with addresses, from the list returned by
SIOCGIFCONF, they won't get added again).
Clean up the error handling a bit.
whether we have "freeifaddrs()" (we don't check whether we have
"getifaddrs()", and if we have "getifaddrs()" but not "freeifaddrs()",
we're stuck with leaking memory).
Give the "any" device an instance number of INT_MAX, so it shows up
after all other non-loopback devices.
"getifaddrs()" sometimes appears to supply a destination address even
for non-point-to-point interfaces (it did so on a FreeBSD 4.1 system);
don't use the broadcast address it supplies if an interface isn't a
broadcast interface, and don't use the destination address it supplies
if an interface isn't a point-to-point interface.
If we had an error constructing the list of interfaces, don't attempt to
add the "any" device to the list.
SOL_PACKET/PACKET_STATISTICS "getsockopt()" call, on Linux kernels that
support it, to get packet statistics, so that we can report the number
of dropped packets, and always use <linux/if_packet.h> to get
definitions for PF_PACKET sockets, so that we don't depend on glibc's
header files having been updated to support all the latest shiniest
kernel features (many systems with 2.4[.x] kernels don't have a
<netpacket/packet.h> that defines "struct tpacket_stats", for example,
so we wouldn't have been able to support that kernel feature on those
systems).
