Add a #define to enable parser tracing.
Clean up parser state when finished parsing, even if we stopped
parsing due to a syntax error, so that there's nothing left
around to screw up the next parse.

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.

move the code from "dfilter_lookup_token()" into
"proto_registrar_get_byname()", and get rid of "dfilter_lookup_token()"
and have its callers call "proto_registrar_get_byname()" instead.

"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/").

Put a hash-table of "interesting" fields in the per-proto-tree data.
The dfilter code records which fields/protocols are "interesting" (by which
I mean, their value or existence is checked). Thus, the proto_tree routines
can create special arrays of field_info*'s that are ready for the dfilter
engine to use during a filter operation.
Also store the "proto_tree_is_visible" boolean, renamed "visible", in
the per-proto-tree data.
Move epan_dissect_t to its own header file to make #include dependencies
easier to handle.
Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t*
as an argument.
epan_dissect_new() needs to be followed by epan_dissect_run() for the
dissection to actually take place. Between those two calls,
epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to
prime the empty proto_tree with the "intersesting" fields from the dfilter_t.

take fully-prototyped function arguments with types appropriate to
"g_malloc()" and "g_free()", and change the calls to the functions
pointed to by those arguments not pass the extra __FILE__ and __LINE__
arguments.

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.
