[PATCH spice-gtk v2] main: Handle lack of free space for file transfer

[Jakub Janků <janku.jakub.jj@xxxxxxxxx>]

Agent can send FileXferStatusMessage with result
VD_AGENT_FILE_XFER_STATUS_NOT_ENOUGH_SPACE together with info about
amount of available free space when the file to transfer is too large
and the client announces support of this result by sending
VD_AGENT_CAP_FILE_XFER_DETAILED_ERRORS
