[Spice-devel] [PATCH win-vdagent] Don't exit when receiving unknown messages

[Jonathon Jongsma]

In 8251fa25, a check on the minimum size of a message was introduced.
For unsupported messages, the vdagent simply exited. This makes it
difficult to extend the vdagent protocol without breaking old
installations. Instead, just print a warning indicating that an
unsupported message was received and ignore it.
