[PATCH v3 0/7] ui: add vdagent implementation and clipboard support.

[Gerd Hoffmann <kraxel@redhat.com>]

Fist sketch of cut+paste support for vnc.  On the guest side we are
going to reuse the spice vdagent, so things should work out-of-the-box
with guests in the wild.  So this patch set brings a qemu implemenation
of the vdagent protocol.

Beside that there is the clipboard infrastructure of course.  For now
only text support is there.  The design allows adding more data types,
so we can add image support and maybe more later on.  So far vdagent,
vnc server and gtk ui are hooked up.

Usage: qemu \
  -chardev vdagent,id=vdagent,clipboard=on \
  -device virtio-serial-pci \
  -device virtserialport,chardev=vdagent,name=com.redhat.spice.0

v2:
 - add a bunch of sanity checks.
 - add proper chunking.
 - use autofree.
v3:
 - support agents without VD_AGENT_CAP_CLIPBOARD_SELECTION.
 - properly parse chunked messages.
 - test with windows guests, minor fixes.
 - set display_id for agent mouse events.
