QGA calls qemu_open_old() in various places. Calling qemu_open() instead isn't a great alternative, as it has special "/dev/fdset" handling and depends on QEMU internal monitor data structures. Instead, provide a simple helper for QGA needs, with Error* support. The following patches will make use of it.
