[Mesa-dev] [PATCH 1] wayland-egl: Add api to get window/pixmap attributes (enable libva over wayland)

[Zhao, Halley]

Resend the patch, it is required to enable libva over wayland.

Ian/Eric:
Could you help to review this patch?

== patch description ==:
wl_egl_window/wl_egl_pixmap are implemented in mesa, however these drawables can also be update in video/camera modules.
An example is that libva also manage buffer object for it, so the attributes of the drawable should be accessed outside of mesa.
With this patch, we can remove the hack to copy wayland-egl-priv.h from mesa to libva.

Libva related changes are here for your reference: https://gitorious.org/libva-wayland/libva-wayland/commits/wayland
It bases on Benjamin's work to enable libva for wayland: http://cgit.freedesktop.org/~bnf/libva/log/?h=wayland
