[PATCH v3 00/18] Clipboard fixes (for 6.1?)

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

Here is a few fixes I have collected while working on clipboard-related code.

There are some obvious code improvements/fixes, and better handling of release &
unregister to avoid dangling pointers and improve user experience.

v3:
 - add a migration blocker
 - improve the code by using a few helpers

v2:
 - replaced "ui/vdagent: unregister clipboard peer on finalize" with 
"ui/vdagent: disconnect handlers and reset state on finalize" patch.
 - added "ui/vdagent: reset outbuf on disconnect"
 - commit message tweaks

Marc-André Lureau (18):
  ui/vdagent: fix leak on error path
  ui/vdagent: remove copy-pasta comment
  ui/gtk-clipboard: use existing macros
  ui/gtk-clipboard: fix clipboard enum typo
  ui/clipboard: add helper to retrieve current clipboard
  ui/clipboard: add qemu_clipboard_peer_owns() helper
  ui/clipboard: add qemu_clipboard_peer_release() helper
