Log Message:
Changes 6.6.2:
Fixed tcpdump.c to trace IP packets buried under VLAN headers.

Changes 6.6.3:
Added a function MissingData() in trace.c to check if TCP segments were
missing or were truncated when the -e option is given to extract
contents.

Changes 6.6.4:
Adding in the INBOUNDS module into the main tcptrace development tree.
It is NOT built in by default though; you need to uncomment a line in
Makefile.in to enable it.

Changes 6.6.5:
* Josh fixed the file format searching order, putting tcpdump format to
the end in file_formats.h as a work around for libpcap brokenness.
* Fixed Mfopen() in mfiles.c to open content data files that we
generate in "binary" mode - by changing fopen mode from "w" \ 
to "wb+" and "a"
to "ab+". The 'b' is dummy in UNIX systems, but seems to have some
semantic in the Windows world.
* Fixed QuitSig() function in tcptrace.c by adding a call to
udptrace_done() so that we print out UDP connection stats too (if one
were piping live tcpdump traffic to tcptrace and "ctrl-c"-ed it in the
middle, for example). On the way, also fixed the arbitrary "buf[4096]"
declaration to be written correctly as "buf[COMP_HDR_SIZE]" in the
PipeFitting() function.

Changes 6.6.6:
Fixed the callback function in tcpdump.c to prevent garbage data from
getting into the ip_buf buffer.

Changes 6.6.7:
Fixed bugs found in the AVL search function that had major bugs /
complexity issues.
