From Gisle Vanem: When saving to a file with "-w", have the "-v" flag make tcpdump report, every 10 seconds, the number of packets captured. Include <smi.h> if we're building with libsmi, to declare "smiInit()" and "smiLoadModule()".

Do the same sort of checks whether ether_ntohost() is declared that we do in libpcap for ether_hostton(). Include <netinet/ether.h> only if it declares ether_ntohost(). If nothing declares it, declare it ourselves, as we do in libpcap. Don't cast the second argument to ether_ntohost() to a const pointer, as some systems don't modify it but don't declare that argument as a const pointer. (This is similar to what we do on libpvap for ether_hostton().) Fix indentation.

#undef HAVE_FCNTL_H
Add support for nommu systems. Rather than hardcode the WIN32 define, add proper fork checks to the configure script and check those. This fixes building for nommu systems which lack the fork function. While we're here though, add support for this functionality via vfork so that it does work on nommu systems. And fix an old bug where we exit properly in the forked child when the exec failed instead of just returning to the calling code (which isn't expecting it). Reviewed-By: Guy Harris <guy@alum.mit.edu>

Use getopt_long(). This requires us to check for it in the configure script and to include a version of getopt_long() for the benefit of platforms that don't have it; we pick up the FreeBSD version and tweak it a bit (eliminating some features specific to the BSD version of getopt_long(), as we want to use it only in a fashion portable to Linux/*BSD/Solaris/etc.) We also get rid of the version of getopt() we supply for Windows in favor of the version of getopt_long() we provide.

Don't require IPv6 library support in order to support IPv6 addresses. Have our own routines to convert between IPv4/IPv6 addresses and strings; that helps if, for example, we want to build binary versions of tcpdump for Windows that can run both on NT 5 (W2K/WXP), which doesn't have inet_ntop() or inet_pton(), and NT 6 (Vista/7/8/10), which do. It also means that we don't require IPv6 library support on UN*X to print addresses (if somebody wants to build tcpdump for older UN*Xes lacking IPv6 support in the system library or in add-on libraries). Get rid of files in the missing directory that we don't need, and various no-longer-necessary autoconf tests.

We support building tcpdump with versions of libpcap other than the one with which it was released, and DLT_BLUETOOTH_HCI_H4_WITH_PHDR might be defined by pcap-bpf.h without pcap/bluetooth.h being present (as appears to be the case on Fedora 9, for example), so check whether <pcap/bluetooth.h> is usable. Update a comment - F9 appears to have a "/usr/include/pcap.h" if you install the libpcap headers. When adding -I flags when running a compiler-based test, add them to CPPFLAGS, not CFLAGS - the latter doesn't work right with AC_CHECK_HEADERS, as the "gcc -E" run doesn't have the -I flags added.

/* Define to 1 if you have the `pcap_breakloop' function. */
Check whether we have "pcap_breakloop()", and use it if we do - it's a safer way to terminate "pcap_loop()" in a signal handler (it just sets a flag, it doesn't muck with data structures that might have been in the middle of being updated). Have "setsignal()" not request SA_RESTART, so that if we call "pcap_breakloop()" in a signal handler and then return, we don't restart a call that was waiting for captured packets, we just make that call EINTR out.

Add support for nommu systems. Rather than hardcode the WIN32 define, add proper fork checks to the configure script and check those. This fixes building for nommu systems which lack the fork function. While we're here though, add support for this functionality via vfork so that it does work on nommu systems. And fix an old bug where we exit properly in the forked child when the exec failed instead of just returning to the calling code (which isn't expecting it). Reviewed-By: Guy Harris <guy@alum.mit.edu>

Check for __attribute__ ((fallthrough)) (GCC 7). The documentation claims that recent GCC is now better by default at spotting cases of code flow falling through (which is true) and that it avoids false positives by matching nearby source code comments with regexps. However, the latter feature doesn't seem to work as reliably as the manual describes it, so let's have a macro for this purpose. Tested to work on: * x86_64, Fedora 26, GCC 7.1.1 (w/__attribute__, w/fallthrough) * x86_64, Ubuntu 16.04, GCC 5.4.0 (w/__attribute__, w/o fallthrough) * x86_64, FreeBSD 11.0, CLang 3.8.0 (w/__attribute__, w/o fallthrough) * SPARC, Solaris 10, SolStudio 12.4 (w/__attribute__, w/o fallthrough) * SPARC, Solaris 10, SunStudio 11 (w/o __attribute__)

We still need u_intN_t. Some libpcap headers use them, and even if we change libpcap to use uintN_t, we don't require that tcpdump 4.x go with libpcap 1.x - we allow people to install the latest tcpdump even if they have an older libpcap and don't want to install a newer one. However, we now define them in terms of the C99 uintN_t types, rather than trying to guess what's appropriate; using unsigned long long for u_int64_t meant that, on some platforms, u_int64_t didn't match PRI[doux]64, and using unsigned long obviously won't work on ILP32 platforms. Also, we already had calls to the autoconf macros for C99 types; get rid of the ones we added. Also also, clean up a comment in tcpdump-stdinc.h.

Fix build issues with the OpenFlow printer on some systems. Don't assume we have <stdint.h>. Instead, use the AC_TYPE_ macros to ensure we have the C99 intN_t and uintN_t types; we already include <inttypes.h> in tcpdump-stdinc.h iff we have it. Get rid of the structure declarations in openflow-1.0.h, as they have zero-length arrays (not supported by all the compilers people might be using) and as 1) they're only used in sizeof() and 2) after each one there's an assertion to check that sizeof() returns a specific numerical value so, instead, just #define various _LEN items to those numerical values and use them. Add an openflow.h header with a #define for the length of the basic header, and move the declaration of of10_header_body_print() there.

C compilers can, and some do, optimize away pointer underflow checks. Cast the pointers to uintptr_t; use AC_TYPE_UINTPTR_T to get uintptr_t defined on older platforms that don't define it themselves.
