And, as we require at least autoconf 2.61, and as autoconf 2.61 and
later have AC_TYPE_UINTn_T and AC_TYPE_INTn_T macros, we use them to
define the uintN_t and intN_t macros if the system doesn't define them
for us.
This lets us get rid of bitypes.h as well.

Have them take a netdissect_options * argument, and get the "no name
resolution" flag from it.
Move the declaration of dnaddr_string to addrtoname.h, along with the
other XXX-to-string routines.

Also add/remove tabs in a few involved functions to justify indentation.

This change converts DVMRP, DLT_ENC, EGP, GeoNet, NetFlow, SLIP and TFTP
decoders.

This change converts IGMP, IPv6 mobility options, LDP, Lightweight
Access Point, PGM, PPTP and RIP decoders.

Remove lots of $Header's and a few $Id's that all belong to the former
CVS repository of tcpdump itself. These keywords have been frozen since
the migration to git in late 2008.

For each decoder that has more than one instance of truncation signaling
and prints the same string in each instance make sure that the string is
declared as "static const char tstr[]" right after the initial includes
block. Where necessary, replace fputs(s, stdout) with equivalent
printf("%s", s).

Make sure all of them are declared const and most of them -- static.
Proper declaration of token arrays is a common review point for new code
that is based on existing decoders. Thus fix the issue at its root.

60 seconds == 600 in units of 0.1, oops.

If it's less than 60 seconds, print it as %.1fs, to be able to
accurately represent small values including the tenths-of-a-second.
Only use relts_print() when it is 60 seconds or more.

The Wireshark routine is based on the BSD in-kernel portable checksum
routine (thus BSD-licensed); it takes a vector of pointers and lengths
and checksums the concatenation of the buffers in question (just as the
BSD in-kernel routine checksums a chain of mbufs).
This simplifies the "with a pseudo-header" checksums; hopefully it'll
fix up the problems being seen on some big-endian platforms, which might
be due to hand-calculating some or all of the checksum and doing so
incorrectly. It also gets rid of some code that might be dereferencing
unaligned pointers.

Instead of checking that there are 8 bytes available at the beginning of
an IGMP packet - which there might not be, e.g. with some DVMRP packets
- do the checks as necessary before fetching values.

appropriately, and that GNUmakefile and the MSVC++ project file define
it apppriately, as we do with libpcap, rather than defining it in
"interface.h".
Undo the rcsid-shuffling and addition of extra #includes, as we no
longer need to arrange that "interface.h" be included before using _U_
in an RCS ID or copyright.

use "_U_" in the definitions of "rcsid[]", to eliminate
complaints about those variables being unused;
move the definitions after the include of "interface.h", or add
an include of "interface.h", so that "_U_" is defined.
Include "config.h" before including "tcpdump-stdinc.h" in
"missing/datalinks.c".

compile with Sun C, as "interface.h" isn't being included before the
structures are being declared.
Furthermore, in the files that Sun C *can* compile, it doesn't cause Sun
C to generate code that's safe with unaligned accesses, as
"__attribute__" is defined as a do-nothing macro with compilers that
don't support it.
Therefore, we get rid of that tag on the structures to which it was
added, and instead use "EXTRACT_16BIT()" and "EXTRACT_32BIT()" to fetch
16-bit and 32-bit big-endian quantities from packets. We also fix some
other references to multi-byte quantities to get rid of code that tries
to do unaligned loads on platforms that don't support them.
We also throw in a hack that makes those macros use
"__attribute__((packed))" on structures containing only one 16-bit or
32-bit integer to get the compiler to generate unaligned-safe code
rather than doing it by hand. (GCC on SPARC produces the same code that
doing it by hand does; I don't know if GCC on any other big-endian
strict-alignment processor generates better code for that case. On
little-endian processors, as "ntohs()" and "ntohl()" might be functions,
that might actually produce worse code.)
Fix some places to use "%u" rather than "%d" to print unsigned
quantities.

unused-parameter problems reported by GCC. Add an _U_ tag to label
parameters as unused if the function is called through a pointer (so
that you can't change its signature by removing parameters) or if there
are unused parameters only because the function isn't complete.
Add some additional bounds checks the necessity for which was revealed
while cleaning up unused-parameter problems.
Make some routines static.
"lcp_print()", defined in "print-lcp.c", isn't called anywhere -
"print-ppp.c" has the code to dissect LCP. Get rid of "print-lcp.c".

Use const more.
Use EXTRACT_* macros more.
Use TCHECK* more.
Use tok2str() to replace some home-grown workalikes.
smb:
- Get rid of private types, use tcpdump-defined types
- Rename fdata and fdata1 to smb_fdata and smb_fdata1 to avoid conflict
with IRIX library function.
