Add tcpdump and libpcap.
- Update the file builder generator to handle generator specific cflags and includes. The tcpdump and libpcap have localised headers and need specific headers paths to see them. There are also module specific flags and these need to be passed to the lex and yacc generators. - Add the tcpdump support.

+ * We don't write DLT_* values to capture files, because they're not the
+ * same on all platforms.
+ *
+ * Unfortunately, the various flavors of BSD have not always used the same
+ * numerical values for the same data types, and various patches to
+ * libpcap for non-BSD OSes have added their own DLT_* codes for link
+ * layer encapsulation types seen on those OSes, and those codes have had,
+ * in some cases, values that were also used, on other platforms, for other
+ * link layer encapsulation types.
+ *
+ * This means that capture files of a type whose numerical DLT_* code
+ * means different things on different BSDs, or with different versions
+ * of libpcap, can't always be read on systems other than those like
+ * the one running on the machine on which the capture was made.
+ *
+ * Instead, we define here a set of LINKTYPE_* codes, and map DLT_* codes
+ * to LINKTYPE_* codes when writing a savefile header, and map LINKTYPE_*
+ * codes to DLT_* codes when reading a savefile header.
+ *
+ * For those DLT_* codes that have, as far as we know, the same values on
+ * all platforms (DLT_NULL through DLT_FDDI), we define LINKTYPE_xxx as
+ * DLT_xxx; that way, captures of those types can still be read by
+ * versions of libpcap that map LINKTYPE_* values to DLT_* values, and
+ * captures of those types written by versions of libpcap that map DLT_
+ * values to LINKTYPE_ values can still be read by older versions
+ * of libpcap.
+ *
+ * The other LINKTYPE_* codes are given values starting at 100, in the
+ * hopes that no DLT_* code will be given one of those values.
+ *
+ * In order to ensure that a given LINKTYPE_* code's value will refer to
+ * the same encapsulation type on all platforms, you should not allocate
+ * a new LINKTYPE_* value without consulting
+ * "tcpdump-workers@lists.tcpdump.org". The tcpdump developers will
+ * allocate a value for you, and will not subsequently allocate it to
+ * anybody else; that value will be added to the "pcap.h" in the
+ * tcpdump.org Git repository, so that a future libpcap release will
+ * include it.
+ *
+ * You should, if possible, also contribute patches to libpcap and tcpdump
+ * to handle the new encapsulation type, so that they can also be checked
+ * into the tcpdump.org Git repository and so that they will appear in
+ * future libpcap and tcpdump releases.
+ *
+ * Do *NOT* assume that any values after the largest value in this file
+ * are available; you might not have the most up-to-date version of this
+ * file, and new values after that one might have been assigned. Also,
+ * do *NOT* use any values below 100 - those might already have been
+ * taken by one (or more!) organizations.
+ *
+ * Any platform that defines additional DLT_* codes should:
+ *
+ * request a LINKTYPE_* code and value from tcpdump.org,
+ * as per the above;
+ *
+ * add, in their version of libpcap, an entry to map
+ * those DLT_* codes to the corresponding LINKTYPE_*
+ * code;
+ *
+ * redefine, in their "net/bpf.h", any DLT_* values
+ * that collide with the values used by their additional
+ * DLT_* codes, to remove those collisions (but without
+ * making them collide with any of the LINKTYPE_*
+ * values equal to 50 or above; they should also avoid
+ * defining DLT_* values that collide with those
+ * LINKTYPE_* values, either).
