Replace:
g_snprintf() -> snprintf()
g_vsnprintf() -> vsnprintf()
g_strdup_printf() -> ws_strdup_printf()
g_strdup_vprintf() -> ws_strdup_vprintf()
This is more portable, user-friendly and faster on platforms
where GLib does not like the native I/O.

Have it take a format and argument list as arguments, and have the
formatting done inside the reporting code. That way, we're not relying
on any particular wmem scope working.
If WIRESHARK_ABORT_ON_DISSECTOR_BUG is set, try to add the message to
the crash information (currently only supported in macOS), and print it
to the standard error, before crashing. We won't necessarily have a
usable crash dump to analyze, so we can't rely on that to find the cause
of the crash.

For a sane plugin build environment. Include config.h as the first
header in the .c file instead.
Fix by moving required compiler attribute macros to a new
"ws_attributes.h" API header.

Having to define two macros for marking a function as never returning
seems a bit redundant. Merge the MSVC and GCC-like attributes into a
single WS_NORETURN.
Tested with Clang 3.7.1, GCC 4.4.7 and even GCC 4.1.2 using this small
program (-Wall -Wextra, the first two generate warnings for
uninitialized variables, the last one compiles without warnings):
#include <stdlib.h>
__attribute__((noreturn)) void foo() { exit(1); }
__attribute__((noreturn)) void bar();
void bar() { exit(1); }
int main() {
int j, i;
if (i) { bar(); return j; }
foo();
return j;
}

The WRETH dissector showed up some garbage in the column display. Upon
further inspection, it turns out that the format string had a trailing
percent sign which caused (unsigned)-1 to be returned by
g_printf_string_upper_bound (in emem_strdup_vprintf). Then ep_alloc is
called with (unsigned)-1 + 1 = 0 memory, no wonder that garbage shows
up. ASAN could not even catch this error because EP is in charge of
this.
So, start adding G_GNUC_PRINTF annotations in each header that uses
the "fmt" or "format" paramters (grepped + awk). This revealed some
other errors. The NCP2222 dissector was missing a format string (not
a security vuln though).
Many dissectors used val_to_str with a constant (but empty) string,
these have been replaced by val_to_str_const. ASN.1 dissectors
were regenerated for this.
Minor: the mate plugin used "%X" instead of "%p" for a pointer type.
The ncp2222 dissector and wimax plugin gained modelines.

tvbuff_init(), tvbuff_cleanup(), reassemble_init(), and
reassemble_cleanup() since they were only used for older GLib versions
which didn't support GSlices. Assume we always support the "matches"

The exception throwing code in except.c/h should be annotated with
"noreturn" to indicate that they never return. Running static analysis
on Wireshark without this annotation causes a lot of false positives
since these analyzers assume that the exception handling code are
ordinary functions that will eventually return.

message not be const (as we generate messages with "g_strdup_sprintf()",
which means they need to be freed; using a null message means that we
don't have to use a special string for exceptions with no message, and
don't have to worry about not freeing that).
Have THROW() throw an exception with a null message pointer. (This
means that you crash if you throw DissectorError with THROW(). Don't do
that - it means you don't get a more detailed explanation of the
dissector problem. Use the DISSECTOR_ASSERT, etc. macros in
epan/proto.h instead.)
Free the exception message for DissectorError, as it's mallocated.

Defect number: 0011
Date: Jul 26 2001
Releases of Kazlib affected: 1.10 through 1.19
Status: Fixed in 1.20
Modules affected: except.c
Description: Members of the except_t structure needed to be declared
volatile because the structure is automatically allocated in the
except macro, modified after a setjmp() takes place, and accessed
after control returns via longjmp.
Solution: Upgrade to 1.20 or backpatch the fix.
