ui/console: new dmabuf.h and dmabuf.c for QemuDmaBuf struct and helpers

New header and source files are added for containing QemuDmaBuf struct
definition and newly introduced helpers for creating/freeing the struct
and accessing its data.

v10: Change the license type for both dmabuf.h and dmabuf.c from MIT to
GPL to be in line with QEMU's default license

v11: -- Added new helpers, qemu_dmabuf_close for closing dmabuf->fd,
qemu_dmabuf_dup_fd for duplicating dmabuf->fd
(Daniel P. Berrangé <berrange@redhat.com>)

-- Let qemu_dmabuf_fee to call qemu_dmabuf_close before freeing
the struct to make sure fd is closed.
(Daniel P. Berrangé <berrange@redhat.com>)

v12: Not closing fd in qemu_dmabuf_free because there are cases fd
should still be available even after the struct is destroyed
(e.g. virtio-gpu: res->dmabuf_fd).

ui/vnc: Do not use console_select()

console_select() is shared by other displays and a console_select() call
from one of them triggers console switching also in ui/curses,
circumventing key state reinitialization that needs to be performed in
preparation and resulting in stuck keys.

Use its internal state to track the current active console to prevent
such a surprise console switch.

ui/console: allow to override the default VC

If a display is backed by a specialized VC, allow to override the
default "vc:80Cx24C".

As suggested by Paolo, if the display doesn't implement a VC (get_vc()
returns NULL), use a fallback that will use a muxed console on stdio.

This changes the behaviour of "qemu -display none", to create a muxed
serial/monitor by default (on TTY & not daemonized).
