master-branch libpcap now generates a reentrant Flex scanner and
Bison/Berkeley YACC parser for capture filter expressions, so it
requires versions of Flex and Bison/Berkeley YACC that support that.
We might as well do the same. For libwiretap, it means we could
actually have multiple K12 text or Ascend/Lucent text files open at the
same time. For libwireshark, it might not be as useful, as we only read
configuration files at startup (which should only happen once, in one
thread) or on demand (in which case, if we ever support multiple threads
running libwireshark, we'd need a mutex to ensure that only one file
reads it), but it's still the right thing to do.
We also require a version of Flex that can write out a header file, so
we change the runlex script to generate the header file ourselves. This
means we require a version of Flex new enough to support --header-file.
Clean up some other stuff encountered in the process.

Tweak lemonflex-tail.inc to fix an issue this reveals.
It appears that, at least on the buildbots, the Visual Studio compiler
no longer issues warnings for the code generated with %option noyywrap.

We don't have any Flex scanners that support an interactive command-line
interface, so none of our scanners are, or need to be, interactive.
Mark text2pcap's scanner as not interactive.
That means none of our scanners should call isatty(), so they don't have
any need to include <io.h> on Windows; remove that include from the
Lucent/Ascent text capture scanner.
Update a comment to reflect that what matters isn't whether we can read
from a terminal or whether we actually do so, what matters is whether
they read *interactively* from a terminal (if you want to run text2pcap
reading from the standard input and type at it, be my guest).

g_string_free(str, FALSE) frees the GString container but not the
underlying g_malloc()ed string; instead, it returns a pointer to the
g_malloc()ed string.
Fix those places that didn't already get the string pointer from
g_string_free() to do so rather than manually extracting the string
themselves.
And fix one place that didn't even need to use a string - it was just
scanning a C string without even modifying it.

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.

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().
Change some data types to avoid those implicit conversion warnings.
When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.
Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers. Cast
away those warnings in some cases where an API we don't control forces
us to do so.
Enable a bunch of additional warnings by default. Note why at least
some of the other warnings aren't enabled.
randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.
If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Add a configuration parameter of the NWG version for WiMAX ASN CP dissector.
The format and meaning of TLVs, as well as function types and messages changed
between the different NWG versions.
Added support for the version number of TLVs in the dictionary xml, its parser,
and of course in the packet itself.
Added support for the version number of function-types and message-types by
extending the value_string structure to contain also a "since" version number.
Successfully tested with a live capture and capture file, containing WiMAX ASN
packets (full Network entry).
Also fuzzed 500 passes successfully.
The XML doesn't contain all existing NWG versions, only selected ones. This is
a little tedious work to go over all TLVs of each version, so I'll add some
newer versions later on. can add a short how-to of adding a new version, for
others to use, if needed.
