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).
