agent: Add support for reporting on free space

Browse Source 
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.

Add VD_AGENT_CAP_FILE_XFER_DETAILED_ERRORS to ensure detailed errors
are not sent to clients that do not support it. This can be used
with more file xfer errors in the future.
