[PATCH v9 2/6] ui/console: new dmabuf.h and dmabuf.c for QemuDmaBuf struct and helpers

[dongwon . kim]

From: Dongwon Kim <dongwon.kim@intel.com>

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.
