escape sequences; sscanf is a bit heavyweight, and using strtoul() also
squelches some "return value ignored" warnings.

so that the config.h definitions are available before we include
anything else; that way, for example, anything defined to enable
large-file support will be defined before we include any system header
files that might depend on it.

Fixes "missing unistd.h" and yywrap "mismatched parameter" warnings

such as the fact that Flex strips all but the last component of the "-o"
argument, and that it doesn't generate a header file to declare routines
the generated lexical analyzer defines. Use that script when building
lexical analyzers, and, for each lexical analyzer, include the generated
header file in the generated analyzer.

Move the %options to the beginning if they weren't already there, and
put them in the same order in all files.
Add "prefix=" options to .l files that don't already have them, so we
don't have to pass a "-P" option.
Add "never-interactive" and "noyywrap" options to our lexical analyzers,
to remove extra isatty() checks and to eliminate the need for yywrap()
from the Flex library.
Get rid of %option nostdinit - that's the default.
Add .l.c: rules to Makefile.am files, replacing the rules for specific
.l files. Have those rules all check that $(LEX) is set.
Update the address for the FSF.

in fact, as we're doing it ourselves but not freeing the result, we leak
memory).

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

on success, so we clear it before calling them.
Assign the value of "strtol()" to a "long" and assign the value of
"strtoul()" to an "unsigned long", as those are the return types for
those functions - "gint32" and "guint32" might not be large enough for
the return value on an LP64 platform.
Check for errno being EINVAL, as that can happen if the number isn't
valid.
Before assigning the value returned by "strtol()" or "strtoul()" to the
final destination, check whether it's in the right range for that
destination.

Use gint32 instead of guint32 for node data.
Fix up some other signed-vs-unsigned issues in the display filter
parser and lexical analyzer.

Use gint32 instead of guint32 and strtol() instead of strtoul()
for signed integers.
Pathological slice specifications could cause Flex default rule

analyzer on errors, and check for SCAN_FAILED from the lexical analyzer
and abort the parse if we see it; 0 means "end of input", and we want to
distinguish errors from end-of-input, so that we can report errors as
such.
If we see end-of-input while parsing a double-quoted string, report the
error (missing closing quote).
Fix the URL for the "Start conditions" section of the Flex manual.

New "matches" operater in display filter language. Uses PCRE.
If a "matches" operator is found in a dfilter
while libpcre has not been used to build the binary, then an
exception is thrown after using dfilter_fail() to set an apporporiate
error message.

Besides "STRING", there is now "UNPARSED_STRING", where the distinction
is that "STRING" was a double-quoted string and "UNPARSED_STRING" is just
a sequence of characters that the scanner didn't know how to scan/parse,
so it's up to the Ftype to parse it.
This gives us more flexibility and prepares the dfilter parsing engine
for the upcoming addition of the "contains" operator.
In the process of doing this, I also re-did the double-quoted string
support in the scanner, so that instead of the naively-simple support we
used to have, double-quoted strings now can have embedded dobule-quotes,
embedded octal sequences, and embedded hexadecimal sequences:
"\"" embedded double-quote
"\110" embedded octal
"\x48" embedded hex
Enhance the dfilter unit test script to be able to run a single collection
of tests instead of having to run all of them all the time.

into epan/ftypes.
Re-write display filter routines using Lemon parser instead of yacc.
Besides using a different tool, the new grammar is much simpler, while
the display filter engine itself is more powerful and more easily extended.
Add dftest executable, to test display filter "bytecode" generation.
Add option to "configure" to build dftest or randpkt, both of which are not
built by default.
Implement Ed Warnicke's ideas about dranges in the new display filter and
ftype code.
Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered
as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree,
while FT_PROTOCOL is used for protocols. This was necessary for being
able to make byte slices (ranges) out of protocols, like "frame[0:3]"
Win32 Makefile.nmake's will be added tonight.
