[Spice-devel] [PATCH spice-protocol] agent: Add support for reporting on free space

[Jakub Janků]

Agent can send VDAgentFileXferStatusMessage with result
VD_AGENT_FILE_XFER_STATUS_NOT_ENOUGH_SPACE to indicate lack of free
space. This enables more detailed error reporting, so the user knows
why the file transfer has failed.
