[Spice-devel] [RFC] [PATCH spice-gtk 1/4] DND: Add spice_main_dnd_*() for sending dnd message to guest

[Dunrong Huang]

These functions could send dnd message to guest.

For now, there are two types of messages:
1) VD_AGENT_DND_START: when user drags a file and drop to spice
    client, spice client will send this message to notify guest agent
    to prepare for receiving file, file's name and size are included
    in message's data.

2) VD_AGENT_DND_DATA: the message is used to transfer file content.
