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!
