Boolean in the file format table to "writing requires seeking", give all

This means we don't need to pass the "can't seek" flag to the dump open
routines.

file_read(buf, bsize, count, file) macro is compilant with fread
function and takes elements count+ size of each element, however to make
it compilant with gzread() it always returns number of bytes.
In wiretap file_read() this is not really used, file_read is called
either with bsize set to 1 or count to 1.
Attached patch remove bsize argument from macro.

everybody use it; the places using the old wtap_dump_file_write() were
using it in the same way the old wtap_dump_file_write_all() did.
That also lets us get rid of wtap_dump_file_ferror().
Also, have the new wtap_dump_file_write() check for errors from
gzwrite() and fwrite() differently - the former returns 0 on error, the
latter can return a short write on error.

1/ patches to support the libpcap/SITA format 'WTAP_ENCAP_SITA'.
2/ patches to the LAPB dissector to accept MLP (Multi-link protocol)
(although MLP dissection has _not_ been added (yet)).
3/ New protocol dissectors for:
a) SITA's WAN layer 0 status header,
b) An airline protocol ALC,
c) An airline (and other industry) protocol UTS.
These patches are submitted as a set since the new protocol dissectors are not
useful without the libpcap/SITA related changes, and there is no point in
having those changes without the additional dissectors.
This fixes bug/enhancement 2016.

This is a replacement of the existing decoding of ERF files (Extensible Record
Format from Endace).
For the decoding of the ERF files, according to the "type of record" given in
the ERF header, several decoders can be used. Up to now, the decoder is
determined according to an environment variable, or with a kind of heuristic.
And, all the treatment is done during the file extraction.
The new architecture, will separate the ERF file decoding, and the ERF record
decoding. The ERF records will be decoded with a specific dissector. This
dissector can be configured with options, to replace the environment variable.

Modified to support the header as a pseudo_header rather than as part of
the packet data.
Fixed some calls that fetch data from the USB packet to fetch it in
little-endian byte order.
Got rid of redundant code to get conversation-specific data (the
get_usb_conv_info() call already does that).
For control packets, only parse the setup information if setup_flag is
0.
Don't interpret a control packet as a standard request unless the setup
type is "Standard".

The attached patch adds support for LAPD frames captured using vISDN thru
libpcap. The support has already been included in libpcap.
The patch adds a new wiretap encapsulation, the necessary glue to decode

to support the remote-to-remote frames captured on the ISDN E-Channel.
Please apply ethereal-encap-table.diff before, as it fixes a misalignment in

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...

addition to an error code, an error info string, for

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.)
