32-bit numbers. Separate signed and unsigned accessors have been
added and used where appropriate.
Definitely not for 0.99.5.

print register numbers as unsigned (they're guint32);
when printing a PUT_FVALUE instruction, show the value as well
as the type of the value.
That requires that a bunch of types get to_repr methods; add them for
PCRE (FTREPR_DFILTER-only - show the regular expression as text),
tvbuffs (FTREPR_DFILTER_only - show the data as a hex string), integral
types, string types other than FT_STRING, and FT_IPv6.
That means we can use fvalue_to_string_repr() for FT_IPXNET and FT_IPv6
in proto_construct_dfilter_string(), and that we don't need to handle
integer and floating types specially in MATE.
Fix some problems with the PCRE execution code for tvbuff types.

integers.
Make FT_INT64 and FT_UINT64 add numerical values, rather than byte-array
values, to the protocol tree, and add routines to add specified 64-bit
integer values to the protocol tree.
Use those routines in the RSVP dissector.

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.

then make sure that the FIELD can participate in the relation that
is expressed in the display filter.
Note that tvbuff's *should* be able to participate in == comparisons, etc.,
but those functions need to be added to ftype-tvbuff.c first.

it would make sense to add PCRE support for byte arrays containing an integer
or an IP address.
Avoid lengthy pointer constructs in cmp_matches().

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.

any previously-allocated version first, so that they don't leak memory.
From Olivier Biot: add a "proto_item_append_string()" routine, to append
to the string value a protocol tree item has.
svn path=/trunk/; revision=8821
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.

of their value. Provide such a method for FT_BYTES, FT_UINT_BYTES,
and FT_ETHER. Have proto_alloc_dfilter_string() use the new methods.
This is part of a movement of ftype-related code out of proto.c and
into the ftype code. The immediate effect is that generated display
filters for long byte sequences don't incorrectly have trailing periods
("...") to indicate continuation.

"epan/..." pathnames, so as to avoid collisions with header files in any
of the directories in which we look (e.g., "proto.h", as some other
package has its own "proto.h" file which it installs in the top-level
include directory).
Don't add "-I" flags to search "epan", as that's no longer necessary
(and we want includes of "epan" headers to fail if the "epan/" is left
out, so that we don't re-introduce includes lacking "epan/").

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.
