From Devin Heitmueller: * Break up dissection into separate functions * Added families not already present (based on GAIM source code) * Added entries from the "generic" family not already present * Started to break families and subtypes into constants instead of having hardcoded values (signon and generic are done, others in progress) svn path=/trunk/; revision=6917

* Ethereal - Network traffic analyzer
Fix Gerald's e-mail address - and fix it in "README.developer", so people don't blindly insert the old address into new dissectors, which is probably how it got into the dissectors being fixed here. svn path=/trunk/; revision=3348

Include files from the "epan" directory and subdirectories thereof with "epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). svn path=/trunk/; revision=4586

Replace the types from sys/types.h and netinet/in.h by their glib.h equivalents for the toplevel directory. The removal of winsock2.h will hopefully not cause any problems under MSVC++, as those files using struct timeval still include wtap.h, which still includes winsock2.h. svn path=/trunk/; revision=5932

Replace the types from sys/types.h and netinet/in.h by their glib.h equivalents for the toplevel directory. The removal of winsock2.h will hopefully not cause any problems under MSVC++, as those files using struct timeval still include wtap.h, which still includes winsock2.h. svn path=/trunk/; revision=5932

Have "proto_register_protocol()" build a list of data structures for protocols, in addition to adding structures to the list of filterable fields. Give it an extra argument that specifies a "short name" for the protocol, for use in such places as pinfo->current_proto; the dialog box for constructing filters; the preferences tab for the protocol; and so on (although we're not yet using it in all those places). Make the preference name that appears in the preferences file and the command line for the DIAMETER protocol "diameter", not "Diameter"; the convention is that the name in question be all-lower-case. Make some routines and variables that aren't exported static. Update a comment in the ICP dissector to make it clear that the dissector won't see fragments other than the first fragment of a fragmented datagram. svn path=/trunk/; revision=2810
