Make it easier/less work/less error-prone to create new IPC channel types (i.e. renderer/plugin).Instead of having each message file include the internal one several times with different ifdefs, move that logic to ipc_message_macros.h. Also make the message class starting IDs come from an enum to ensure we don't use a value twice. I simplified the logging code a bit so we don't need X_messages.cc files.Clean up places that we were doing manual packing/unpacking. Most of this was in the automation code. I added a few new template functions to make it convenient to read the parameters from a message, and updated the code to use them.I also removed unnecessary includes of render/plugin_messages.h from headers to speed up compiling.I moved the traits of IPC structs beside the struct definition to make it more apparent what's going on, so we avoid people modifying the struct and forgetting to update the traits.Amit: please look at chrome/test/automation/tab_proxy.ccMarc-Antoine: chrome/browser/printing/*Matt: the rest
