Subject: spice: client: add foreign menu #558248

Spice foreign menu enables external control of the client menu.

The foreignmenu protocol enables an external application to:
add a submenu, set its title, clear it, add/modify/remove an item etc.

Foreign menu is rewritten from scratch, based on the cross-platform named pipe
