libwireshark (and the plugins using those functions) do not depend on
wiretap on Windows.
While doing that, rename the eth_* functions to ws_*.

So far I've done only regression testing (the new functionality and what's in wtap-plugins.c has not yet being tested).
it is a first step in the way to have lua opening files.

fix this, by providing required functions in the new file file_util.c - it's mostly copied from GLib (g_open alike - that take UTF8 as filename format but don't use msvcrt.dll V6 for this as the glib files do)
"link" to these functions in file_util.h: #define eth_open eth_stdio_open
revert changes (from SVN 20282) throughout the code related to these file functions which were introduced with the first tries of MSVC 2005 ...
Hopefully I've done everything right with the new file_util.c ...

currently limited to Ethereal and all the variants of libpcap filetypes only.
We might want to add output compression support to the other tools as well (tethereal, mergecap, ...).
We might also want to add support for the other filetypes, but this is only possible if the filetype functions doesn't use special output operations like fseek.
One bug is still left: if the input and output filetypes while saving are the same, Ethereal currently optimizes this by simply copy the binary file instead of using wiretap (so it will be faster but it will ignore the compress setting).
Don't know a good workaround for this, as I don't know a way to find out if the input file is currently compressed or not. One idea might be to use a heuristic on the filesize (compared to the packet size summmary). Another workaround I see is to remove this optimization, which is of course not the way I like to do it ...

I've done more than a day to change the timestamp resolution from microseconds to nanoseconds. As I really don't want to loose those changes, I'm going to check in the changes I've done so far. Hopefully someone else will give me a helping hand with the things left ...
What's done: I've changed the timestamp resolution from usec to nsec in almost any place in the sources. I've changed parts of the implementation in nstime.s/.h and a lot of places elsewhere.
As I don't understand the editcap source (well, I'm maybe just too tired right now), hopefully someone else might be able to fix this soon.
Doing all those changes, we get native nanosecond timestamp resolution in Ethereal. After fixing all the remaining issues, I'll take a look how to display this in a convenient way...
As I've also changed the wiretap timestamp resolution from usec to nsec we might want to change the wiretap version number...

(so if the file's gzipped, it's *NOT* the size of the file after
uncompressing), and an approximation of the amount of that data read
sequentially so far.
Use those for various progress bars and the like.
Make the fstat() in the Ascend trace reader directly use wth->fd, as
it's inside Wiretap; that gets rid of the last caller of wtap_fd() (as
we're no longer directly using fstat() or lseek() in Ethereal), so get
rid of wtap_fd().

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.

0 means "there is no FCS in the packet data", 4 means "there is an FCS
in the packet data", -1 means "I don't know whether there's an FCS in
the packet data, guess based on the packet size".
Assume that Ethernet encapsulated inside other protocols has no FCS, by
having the "eth" dissector assume that (and not check for an Ethernet
pseudo-header).
Have "ethertype()" take an argument giving the FCS size; pass 0 when
appropriate.
Fix up Wiretap routines to set the pseudo-header. This means we no
longer use the "generic" seek-and-read routine, so get rid of it.

files to get that big.
From Thomas Wittwer and Matthias Nyffenegger:
Support for "ring buffer mode", wherein there's a ring buffer of N
capture files; as each capture file reaches its maximum size (the ring
buffer works only with a maximum capture file size specified), Ethereal
rolls over to the next capture file in the ring buffer, replacing
whatever packets might be in it with new packets.
