ui/vdagent: core infrastructure
The vdagent protocol allows the guest agent (spice-vdagent) and the
spice client exchange messages to implement features which require
guest cooperation, for example clipboard support.
This is a qemu implementation of the spice client side. This allows
the spice guest agent talk to qemu directly when not using the spice
protocol.
usage: qemu \
-chardev qemu-vdagent,id=vdagent \
-device virtserialport,chardev=vdagent,name=com.redhat.spice.0
This patch adds just the protocol basics: initial handshake and
capability negotiation. The following patches will add actual
functionality and also add fields to the initially empty
ChardevVDAgent qapi struct.
