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these have been replaced by val_to_str_const.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.

When ASAN is enabled, a false buffer overflow warning is raised. It is
a false positive since everything starting at '\0' will get ignored by
the PCMPISTRI instruction (see Intel(r) SSE4 Programming Reference,
5.3.1.5 "Valid/Invalid Override of Comparisons", and 5.3.1.2
"Aggregrate Operation", case "Equal any").
Concerns about reading past the end of the page turns out to be false,
there always seem to be a valid page after the current one (for static
and heap memory at least). It is an non-issue since strlen also does
not have issues with this.
Rather than fully disabling SSE 4.2 and using the fallback
implementation for ASAN-enabled builds, read the set of characters from
'a' into the mask without a 128-bit read and then still use SSE 4.2
for the actual query.

With autotools, CMake, and nmake, if we have a function, #define
HAVE_{function_name_in_all_caps}, otherwise don't #define it.
If we provide our own version of a function in libwsutil, make sure we
have a header that declares it, and *ONLY* include that header if
HAVE_{function_name_in_all_caps} is *NOT* defined, so that we don't have
the system declaration and our declaration colliding.
Check for inet_aton, strncasecmp, and strptime with CMake, just as we do
with autotools.
Simplify the addition of {function_name_in_all_caps}_LO to libwsutil in

Add a routine get_ws_vcs_version_info() that, for builds from a tree
checked out from Wireshark's version control system, returns a string
that includes both the Wireshark version number and an indication of
what particular VCS version was checked out, and just returns
Wireshark's version number for other builds.
Use that routine rather than manually gluing VERSION and the Git version
number together.
