Stub in more IPC attachment brokering functionality.
This CL fills in most of the logic for sending a Windows HANDLE from a
non-broker process to the broker process. This consists of several small
changes:
- Create the new IPC messages AttachmentBrokerMsg_WinHandleHasBeenBrokered and
AttachmentBrokerMsg_RequestBrokerageOfWinHandle.
- Add a sender_ member variable to AttachmentBrokerWin.
- Define the wire format for HandleAttachmentWin.
- Add logic to ChannelWin to send
AttachmentBrokerMsg_RequestBrokerageOfWinHandle for each HANDLE attachment.
