Address-and-Control-Field-Compression can be negotiated on, so there's

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...

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.

rather than requiring individual capture file type handlers to do it
(unless they're doing per-packet encapsulation, in which case we check
to make sure they didn't *leave* it as WTAP_ENCAP_PER_PACKET).

addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".

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.

Support writing WTAP_ENCAP_FRELAY_WITH_PHDR and WTAP_ENCAP_PPP_WITH_PHDR

information, but so it goes.
When reading/writing Windows Sniffer format, read and write the
direction flag.

Allow "-" as the output file name in Wiretap, referring to the
standard error.
Optimize the capture loop.
Fix some of the error-message printing code in Ethereal and Tethereal.
Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"
routine. Have the "open for output" routines for files where we need to
seek when writing the file return an error if seeks don't work.

the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.
To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.

"err" argument is null and return an error code through that argument

"struct x25_phdr" to "wiretap/wtap.h".
Have two X.25 dissectors, one of which assumes that there's a "struct
x25_phdr" pseudo-header and one of which doesn't; the former uses the
information in that pseudo-header to determine whether the packet is
DTE->DCE or DCE->DTE, and the latter assumes it has no clue whether the
packet is DTE->DCE or DCE->TDE. Use the former one in the LAPB
dissector, and the latter one in the XOT dissector and in the LLC
dissector table.
In the X.25-over-TCP dissector, handle multiple X.25 packets per TCP
segment, and handle X.25 packets split across TCP segments.

an "err" argument that points to an "int" into which to put an error
code if it fails.
Check for errors in one call to it, and note that we should do so in
other places.
In the "wtap_seek_read()" call in the TCP graphing code, don't overwrite
"cfile.pseudo_header", and make the buffer into which we read the data
WTAP_MAX_PACKET_SIZE bytes, as it should be.
In some of the file readers for text files, check for errors from the
"parse the record header" and "parse the hex dump" routines when reading
sequentially.
In "csids_seek_read()", fix some calls to "file_error()" to check the
error on the random stream (that being what we're reading).

For file types where we allocate private data, add "close" routines
where they were missing, to free the private data. Also fix up the code
to clean up after some errors by freeing private data where that wasn't
being done.
Get rid of unused arguments to "wtap_dump_open_finish()".
Fix indentation.
