Fixes to Q.931 dissector, and additions from a recent copy of Q.931. Export some functions from the Q.931 dissector, so the Q.2931 dissector can use them. Add a pile of information element dissection to the Q.2931 dissector. svn path=/trunk/; revision=1104

/* packet-q931.h
From Kan Sasaki: added some VSAs from the FreeRadius dictionary files and other changes to RADIUS. Export the Q.931 cause location and code values, and use them in the RADIUS dissector for ACC cause codes and values. Make "CHAP" all caps, as it should be, and use InterCaps in AppleTalk (Apple does). The CHAP Challenge is an octet string, not a text string - the FreeRadius dictionary has an error there. In "rdconvertinttostr()", if there's no value_string table, just print the value numerically, don't call "rd_match_strval()". Don't pass a null value_string pointer to "rd_match_strval_attrib()" - just report the value, without attempting to find a string for it. svn path=/trunk/; revision=5460

Miscellaneous code cleaning - add <stdarg.h> or <varargs.h> in snprintf.h and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes - remove the check of multiple inclusions in source (.c) code (there is a bit loss of _cpp_ performance, but I prefer the gain of code reading and maintenance; and nowadays, disk caches and VM are correctly optimized ;-). - protect all (well almost) header files against multiple inclusions - add header (i.e. GPL license) in some include files - reorganize a bit the way header files are included: First: #include <system_include_files> #include <external_package_include_files (e.g. gtk, glib etc.)> Then #include "ethereal_include_files" with the correct HAVE_XXX or NEED_XXX protections. - add some HAVE_XXX checks before including some system header files - add the same HAVE_XXX in wiretap as in ethereal Please forgive me, if I break something (I've only compiled and regression tested on Linux). svn path=/trunk/; revision=2254

Add "tvb_reported_length()" to get the "reported length" of a tvbuff (i.e., the amount of data that was in the packet, even if not all of it was captured), for use when dissecting packets containing data that fills the packet (we want the dissector to try to dissect all of it; if it runs past the end of the captured data, we want it to throw an exception so that we'll put a "Short Frame" note in the protocol tree). This means we always want a tvbuff to have a real reported length value, so we make it an unsigned integer, and don't bother checking it for -1, as it should never be -1. If the reported length passed in to "tvb_set_subset()" is -1, set the reported length to the reported length of the tvbuff of which the new tvbuff will be a subset minus the offset in that tvbuff of the subset, so that "-1" means "what's left of the packet after we chop off the header". This is necessary in order to ensure that all tvbuffs have a real reported length value. Have "dissect_packet()" set the reported length of the top-level tvbuff to the reported length of the frame, so that we start out with a tvbuff with a real reported length value. Have "tvb_offset_exists()" return FALSE if the offset is past the end of the tvbuff. If the offset passed to it is postitive, have "compute_offset_length()" check for that it's not more than one byte past the end of the tvbuff - if it's just past the end, we don't want the check to fail, as we don't want attempts to create a subset tvbuff containing zero bytes to fail; that would be done if a captured packet was all header and no payload, and we'd want the dissector of the payload, not the dissector of the header, to throw an exception, as the problem isn't with the protocol for the header, it's with the protocol for the payload. Convert the ATM dissector, the SSCOP dissector, the Q.2931 dissector, and the Q.931 dissector to use tvbuffs. Make the LAPD dissector set up a tvbuff for the Q.931 dissector (it's not converted yet). svn path=/trunk/; revision=2023
