abc8c2d61c Remove many (762) now redundant ND_TCHECK_n() calls
ND_TCHECK_n(e), n in { 1, 2, 3, 4, 8 }.

They are redundant because they are followed by a GET_.*_n(e) call,
same n, same e, which do the bounds check.

Remove unused 'trunc' labels and most associated codes.

Update the outputs of some tests accordingly.

ee68aa3646 Use the new GET_ macros instead of the EXTRACT_ ones
The exceptions are currently:
Some EXTRACT_ in print-juniper.c, not used on packet buffer pointer.
An EXTRACT_BE_U_3 in addrtoname.c, not always used on packet buffer
pointer.

fb2479d733 Always include <config.h> rather than "config.h".
This can prevent bizarre failures if, for example, you've done a
configuration in the top-level source directory, leaving behind one
config.h file, and then do an out-of-tree build in another directory,
with different configuration options.  This way, we always pick up the
same config.h, in the build directory.

da20bc56d6 Rename EXTRACT_ macros
Now all the macros have a name meaning a count in bytes.

With _S_: signed, _U_: unsigned

e.g.:
EXTRACT_BE_32BITS -> EXTRACT_BE_U_4
EXTRACT_LE_32BITS -> EXTRACT_LE_U_4
...
EXTRACT_BE_INT32 -> EXTRACT_BE_S_4

and have:
EXTRACT_8BITS -> EXTRACT_U_1
EXTRACT_INT8  -> EXTRACT_S_1

38700c7f24 dismiss NETDISSECT_REWORKED macro
The purpose of this macro was to enable the file-by-file switch to NDO,
after which only tcpdump.c had a use of it and the definitions guarded
by it. Update tcpdump.c not to require them any more and dismiss the
unused definitions.

ed85e20e4d u_intN_t is dead, long live uintN_t.
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.

988cd2bb0e Have various routines for printing non-final headers for IPv4/IPv6
return -1 if they run out of data.

Have the IPv4 and IPv6 dissectors check for non-positive return values
from those routines and quit if they see one.

bbc1cfa669 Have the configure script arrange that the Makefile define _U_
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.

3824a6c041 From Neil Spring:
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".

fcc82f451d The "__attribute__((packed))" tag on structures causes some files not to
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.

c422d3ab0f Get rid of the "-Wno-unused" flag, and fix up most of the
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".

 - Rename fdata and fdata1 to smb_fdata and smb_fdata1 to avoid conflict

Move ARP declarations from BSD include files to "print-arp.c".

Remove from dissectors includes of <netinet/if_ether.h>, and add
includes of "ethertype.h" and/or "ether.h" as necessary.

Get rid of configuration options that test declarations now made in
"ether.h" or "print-arp.c", as those declarations are now under our
control, not the OS's control.
