The guest agent doesn't know what is the current serial state. Reset the
serial value whenever a new agent connection is established.

Some files wrongly contain the same word twice in a row.
One of them should be removed or replaced.

Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.
This can help to make some code independent from qemu too.
gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

The current implementation lacks migration support. After migration,
vdagent support will be broken (even after a restart of the daemons).
Let's try to fix it in 6.2.

This patch adds support for clipboard messages to the qemu vdagent
implementation, which allows the guest exchange clipboard data with
qemu. Clipboard support can be enabled/disabled using the new
'clipboard' parameter for the vdagent chardev. Default is off.

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.
