Merge remote-tracking branch 'goog/tcpdump'

* goog/tcpdump: (3066 commits)
  Remove old version. Getting ready for new tcpdump 4.5
  Support -Q for setting the capture direction.
  Clean up the TLV processing loop.
  With -A and -AA, don't send CRs to the standard output.
  Use the new libpcap <pcap/nflog.h> for NFLOG definitions and declarations.
  Do our own isascii(), isprint(), isgraph(), and toascii().
  Fix a compiler warning.
  Don't use the __attribute__((packed)) on most platforms.
  The interval in an AODV HELLO extension is not aligned on a 4-byte boundary.
  As with memcpy, so with memcmp.
  More UNALIGNED_MEM{CPY,CMP} on IP addresses.
  Another case where UNALIGNED_MEMCPY() is probably necessary.
  No need for casting back and forth.
  Only do the unaligned_mem{cpy,cmp} hack if necessary.
  No need to declare unaligned_mem{cpy,cmp} in netdissect.h *and* interface.h.
  More possibly-unaligned memcpy()s and assignments - use unaligned_memcpy().
  Check for compiling for IPv6; don't check whether we can create an IPv6 socket.
  Use unaligned_memcmp() to compare with IPv{4,6} addresses in a packet.
  Use EXTRACT_nBITS even when just testing against zero.
  Fix some more unaligned accesses.

+To build tcpdump under Windows, you need:
+
+- version 6 (or higher) of Microsoft Visual Studio or the Cygnus gnu 
+C compiler.
+- The November 2001 (or later) edition of Microsoft Platform 
+Software Development Kit (SDK), that contains some necessary includes 
+for IPv6 support. You can download it from http://www.microsoft.com/sdk
+- the WinPcap source code, that includes libpcap for win32. Download it
+from http://winpcap.polito.it or download libpcap sources from
+http://www.tcpdump.org and follow the instructions in the README.Win32
+file.
+
+First, extract tcpdump and WinPcap in the same folder, and build WinPcap.
+
+The Visual Studio project and the cygwin makefile are in the Win32\prj
+folder.
+
+From Visual Studio, open windump.dsw and build the program. The release 
+version of the WinDump.exe executable file will be created in the 
+windump\win32\prj\release directory . The debug version will be generated
+in windump\win32\prj\debug.
+
+From cygnus, go to windump\win32\prj\ and type "make". WinDump.exe will be
+created in the same directory.
