memory if it throws an exception, as it checks whether the entire string
is in the tvbuff *before* allocating a buffer for it, and that also
means that if the length is absurdly large, an exception will be thrown,
rather than the memory allocation failing.

This functin was in a recent profiling run the fifth most expensive function.
It consumed ~3.5% of the total cpu in that run.
Using a static table this function is now just over twice as fast as previously.
My testrun calling it 10.000.000 times in a loop changed the execution time from ~17.3s ro ~8.2s
If this test was representative for the speedup and if ~3.5 in the profile run
was representative for normal cases this should make ethereal ~1.8% faster.
Woohoo.
(low hanging fruit)

Make "proto_is_protocol_enabled()" and "proto_get_protocol_short_name()"
take a "protocol_t *" as an argument, so they don't have to look up the
"protocol_t" - this will probably speed them up considerably, and
they're called on almost every dissector handoff.
Get rid of a number of "proto_is_protocol_enabled()" calls that aren't
necessary (dissectors called through handles, including those called
through dissector tables, or called as heuristic dissectors, aren't even
called if their protocol isn't enabled).
Change some direct dissector calls to go through handles.

* Added a new function get_file_in_temp() to
epan/filesystem.c. This because of asn1.dll plugin which
had code to write to a log-file "c:\temp\ethereal.log". I feel
this patch makes this safer; I don't even have a c:\temp dir.
* Patched packet-asn1.c to use get_file_in_temp().
* Added some #undef to packet-snmp.c to silence gcc.
* Changed "%u" -> "%lu" formats in util.c
Rename get_file_in_temp() to get_tempfile_path() to match other function
names.

stub data even if there's a problem dissecting the verifier.
Show stub data as "Encrypted stub data" if it's encrypted, "Decrypted
stub data" if it was encrypted but we decrypted it, and "Stub data" if
it wasn't encrypted.
Don't attempt to decrypt data unless it was encrypted (i.e., the
authentication level is "Packet privacy".
Get rid of "decrypted_data" member of "packet_info" structure - we don't
need it any more.

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.

non-null, set "*exception" to the appropriate exception - its callers
rely on it.
Now that it does that, there's no need for "check_offset_length()" to
check for a length of -1, as "compute_offset_length()" does so, and
therefore "check_offset_length_no_exception()" does so.

Remove the internal packet-per.c functions
"dissect_per_length_determinant()" and
"dissect_per_normally_small_nonnegative_whole_number()" from the
plugin API, as they shouldn't be used outside the PER dissector.
Remove the H.225/H.245 functions
"dissect_h225_TransportAddress()" and
"dissect_h245_NonStandardParameter()" from the plugin API until
we really need them in plugins.
Add the string dissector table functions to the plugin API.

Don't crash if "-z" is used on the command line when a live
capture is being done (e.g., with "-k -S" - in that case,
"cfile.filename" is null when the window is created), just don't
display the file name in the title.
Don't set the title of a non-existent window - create the window
first.

One can now select a packet and mark it as a TimeReference packet using the menu.
A TimeReference packet will be indicated by having all timestamp related column entries replaced by the string *REF*
A TimeReference packet will always be displayed in the packet pane, and overrides any display filters.
When a frame is a TimeReference frame, all later frames will calculate the TimeRelativeToFirstPacket relative to the timestamp of the TimeReference frame instead of the first frame of the capture.
You can have any number of TimeReference frames you like.

Ethereal presents a column to display culmulative bytes into the capture.
A new column type is added : Culmulative Bytes.
While PacketLength column type specifies the number of bytes in the current packet,
Culmulative Bytes specifies the culmulative number of bytes from the start of the capture.

string.)

Create "_buf()" versions of various "to_str" routines for various

them to finish up "address_to_str_buf()".

"packet-sna.h", as that routine has been swallowed up in
"sna_fid_to_str()".
