Simplify the magic required to create IPC message headers a bit.

 // Copyright (c) 2006-2008 The Chromium Authors. All rights reserved.
 // Use of this source code is governed by a BSD-style license that can be
 // found in the LICENSE file.
 
 // This header is meant to be included in multiple passes, hence no traditional
 // header guard.
 //
-// In the first pass, IPC_MESSAGE_MACROS_ENUMS should be defined, which will
-// create enums for each of the messages defined with the IPC_MESSAGE_* macros.
-//
-// In the second pass, either IPC_MESSAGE_MACROS_DEBUGSTRINGS or
-// IPC_MESSAGE_MACROS_CLASSES should be defined (if both, DEBUGSTRINGS takes
-// precedence).  Only one .cc file should have DEBUGSTRINGS defined, as this
-// will create helper functions mapping message types to strings.  Having
-// CLASSES defined will create classes for each of the messages defined with
-// the IPC_MESSAGE_* macros.
+// In your XXX_messages_internal.h file, before defining any messages do:
+//     #define IPC_MESSAGE_START XMsgStart
+// XMstStart value is from the IPCMessageStart enum in ipc_message_utils.h
+// In your XXX_messages.cc file, after all the includes for param types:
+//     #define IPC_MESSAGE_IMPL
+//     #include "X_messages.h"
 //
 // "Sync" messages are just synchronous calls, the Send() call doesn't return
 // until a reply comes back.  Input parameters are first (const TYPE&), and
 // To declare a sync message, use the IPC_SYNC_ macros.  The numbers at the
 // end show how many input/output parameters there are (i.e. 1_2 is 1 in, 2
 // out). The caller does a Send([route id, ], in1, &out1, &out2).
 // The receiver's handler function will be
 //     void OnSyncMessageName(const type1& in1, type2* out1, type3* out2)
 //
 //
 // A caller can also send a synchronous message, while the receiver can respond
 // at a later time.  This is transparent from the sender's side.  The receiver
 // needs to use a different handler that takes in a IPC::Message* as the output
 // type, stash the message, and when it has the data it can Send the message.
 //
 // Use the IPC_MESSAGE_HANDLER_DELAY_REPLY macro instead of IPC_MESSAGE_HANDLER
 //     IPC_MESSAGE_HANDLER_DELAY_REPLY(ViewHostMsg_SyncMessageName,
 //                                     OnSyncMessageName)
 //
 // The handler function will look like:
 //     void OnSyncMessageName(const type1& in1, IPC::Message* reply_msg);
 //
 // Receiver stashes the IPC::Message* pointer, and when it's ready, it does:
 //     ViewHostMsg_SyncMessageName::WriteReplyParams(reply_msg, out1, out2);
 //     Send(reply_msg);
