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

This commit introduces dpy_gl_qemu_dmabuf_get_... helpers to extract
specific fields from the QemuDmaBuf struct. It also updates all instances
where fields within the QemuDmaBuf struct are directly accessed, replacing
them with calls to these new helper functions.

v6: fix typos in helper names in ui/spice-display.c

IMHO these method names don't need a "dpy_gl_" prefix on
them. Since they're accessors for the "QemuDmaBuf" struct,
I think its sufficient to just have "qemu_dmabuf_" as the
name prefix, making names more compact.

The console.{h,c} files are a bit of a dumping ground for
UI code. While QemuDmaBuf was just a struct with direct
field access that's OK.

With turning this into a more of an object with accessors,
I think it would also be desirable to move the struct
definition and all its methods into separate ui/dmabuf.{c,h}
files, so its fully self-contained.

With regards,
Daniel

[Kim, Dongwon] I am ok with changing function names and create
separate c and h for dmabuf helpers as you suggested. But I would
like to hear Marc-André's opinion about this suggestion before I make
such changes.

Marc-André, do you have any thought on Daniel's suggestion?
