Specifically: - Set packet.h to be the first wireshark #include after config.h and "system" #includes. packet.h added as an #include in some cases when missing. - Remove some #includes included (directly/indirectly) in packet.h. E.g., glib.h. (Done only for those files including packet.h). - As needed, move "system" #includes to be after config.h and before wireshark #includes. - Rework various #include file specifications for consistency. - Misc.
