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.

+/*
+ * This module implements decoding of OpenFlow protocol version 1.0 (wire
+ * protocol 0x01). The decoder implements terse (default), detailed (-v) and
+ * full (-vv) output formats and, as much as each format implies, detects and
+ * tries to work around sizing anomalies inside the messages. The decoder marks
+ * up bogus values of selected message fields and decodes partially captured
+ * messages up to the snapshot end. It is based on the specification below:
+ *
+ * [OF10] http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf
+ *
+ * Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT
+ * messages is done only when the verbosity level set by command-line argument
+ * is "-vvv" or higher. In that case the verbosity level is temporarily
+ * decremented by 3 during the nested frame decoding. For example, running
+ * tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
+ * the nested frames.
