Marc-André Lureau e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN
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.

Marc-André Lureau 90208bc965 ui/vdagent: add a migration blocker
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.

Gerd Hoffmann f0349f4d89 ui/vdagent: add clipboard support
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.

Gerd Hoffmann de74a22cc8 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.
