Gilbert Ramirez b2f932c1db Changed the display filter scanner from GLIB's GScanner to lex. The code
as it standed depends on your lex being flex, but that only matters if you're
a developer. The distribution will include the dfilter-scanner.c file, so
that if the user doesn't modify dfilter-scanner.l, he won't need flex to
re-create the *.c file.

The new lex scanner gives me better syntax checking for ether addresses. I
thought I could get by using GScanner, but it simply wasn't powerful enough.

All operands have English-like abbreviations and C-like syntax:
and, && ; or, || ; eq, == ; ne, != ; , etc.

I removed the ETHER_VENDOR type in favor of letting the user use the [x:y]
notation:	ether.src[0:3] == 0:6:29 instead of ether.srcvendor == 00:06:29

I implemented the IPXNET field type; it had been there before, but was
not implemented. I chose to make it use integer values rather than byte
ranges, since an IPX Network is 4 bytes. So a display filter looks like this:
	ipx.srcnet == 0xc0a82c00
rather than this:
	ipx.srcnet == c0:a8:2c:00

I can supposrt the byte-range type IPXNET in the future, very trivially.

I still have more work to do on the parser though. It needs to check ranges
when extracting byte ranges ([x:y]) from packets. And I need to get rid
of those reduce/reduce errors from yacc!

Gilbert Ramirez 0d36ec8de2 Modified the proto_register_field_array usage again. Thanks to Guy's
suggestion, this new method using a static array should use less memory
and be faster. It also has a nice side-effect of making the source-code
more readble, IMHO.

Changed the print routines to look for protocol proto_data instead of
looking at the text label as they did before, hoping that the data hex
dump field item starts with "Data (".

Added the -G keyword to ethereal to make it dump a glossary of display
filter keywords to stdout and exit. This data is then formatted with
the doc/dfilter2pod perl program to pod format, which is combined
with doc/ethereal.pod.template to create doc/ethereal.pod, from which
the ethereal manpage is created. This way we can keep the manpage up-to-date
with a list of fields that can be filtered on.

Gilbert Ramirez 601c52f0fb Added support for compiling on win32 with Visual C and 'nmake'. It compiles,
but does not link. Perhaps someone who understands the MS tools can help
out. I made it link a few months ago, but with different version of glib/gtk+.
I can't remember how I made it link.

Most of the compatibility issues were resolved with adding
#ifdef HAVE_UNISTD_H the the source code. Please be sure to add this to all
future code.

Guy Harris 856e356a7a "const"ifty some function arguments and structure members, and "#if 0"
out the declaration of a variable used only by "#if 0"ed out code, to
eliminate some compiler warnings.

Gilbert Ramirez 07f42b5b31 Created a new protocol tree implementation and a new display filter
mechanism that is built into ethereal. Wiretap is now used to read all
file formats. Libpcap is used only for capturing.
