Anders Broman 1950ffc214 Apply the small performance enhancment patches for:
- if offset is 0, tvb_length is the same as tvb_length_remaining, just faster.
Replace 
- col_append_fstr() with faster  col_append_str() 
- col_add_str() with col_set_str()
when it's safe

Ronnie Sahlberg 2d1bb39121 change the signature for the get_pdu_len() function pointer passed to tcp_dissect_pdus() to also include a packet_info pointer.
there are many reasons why some protocols actually need to be able to access the pinfo structure while determining the pdu size

Gerald Combs 8b315480f1 In new_format_oid(), handle a zero-length OID.
Fix a bug introduced recently in packet-rpc.c.

Replace DISSECTOR_ASSERT() with THROW(ReportedBoundsError) in my recent 
checkins, since fuzz-test.sh sets WIRESHARK_ABORT_ON_DISSECTOR_BUG.

Ronnie Sahlberg f331077a60 waste a couple of bytes per tcp conversation and make the tree for acked_packets (i.e. packets that have interesting tcp properties such as being retransmissions etc) hang off the per conversation tcpd struct instead of being global.
while this should improve performance by unmeasurably little it does have the sideeffect that once we finish the rewrite   tcp analysis might actually work and work well even for tcp over tcp tunnelling. 

this also means that if you include packet-tcp.h   you also need to include emem.h .

Ulf Lamping 9a42ef9536 fix #480: Change defaults for all reassembling settings to ON
I've changed all settings I could find to TRUE. It might be reasonable to change some protocol settings back to FALSE, if reassembling fails very often.

Anders Broman 851ecd2ac4 From Jon Ringle:
1) Added a setup_frame parameter to conversation_t
2) Used the conversation_t next to maintain a list of conversations with the 
same src/dest tuple but different setup_frame number.
3) Changed the signature of find_conversation() and conversation_new() to pass 
in the frame number.
4) Adjusted packet-sdp to select RTP conversation if both m=audio and m=image 
are present, and T.38 conversation if only m=image is present. I expect that 
RTP/T.38 dissecting to be better, but I don't have a way to generate T.38 
packets.

Guy Harris f6024ff41e Don't set a string pointer to point to a constant string if that pointer
will later be handed to a free-memory routine - g_strdup() the constant
string.

Ulf Lamping d530bd4e14 Prevent the word "desegmentation" at the GUI, but use reassembling at that places, as we also use "defragmentation" and "reassembling". Use reassembling as the general term for such actions.
I (hopefully) didn't changed any protocol fields or preference file names, but only the GUI labels appearing in the protocol display and the protocol preferences.

Also added a note to the protocol preferences (where appropriate), that you have to enable "Allow subdissectors to reassemble TCP streams" at the corresponding protocol settings for TCP reassembling to take effect.

If you encounter any mistakes I've made here, please let me know...

Gilbert Ramirez 669db206cb Move dissectors to epan/dissectors directory.
Also move ncp222.py, x11-fields, process-x11-fields.pl,
make-reg-dotc, and make-reg-dotc.py.

Adjust #include lines in files that include packet-*.h
files.
