Initial Wayland integration

Hi,

This is the first round of Wayland integration. The Wayland protocol libraries, optional (based on DISTRO_FEATURE) support for the Wayland EGL backend is added to Mesa, and then Weston is added.

Weston's packaging is rather complicated because it can build multiple backends, but it's flexible enough to cope.

Future plans include an image that boots directly into wayland-on-KMS, and enabling the Wayland support in GTK+ and Qt.

One quirk is that you can build weston without the wayland distro feature, which results in just wayland-on-x11. The distro feature name may have to be split up to reflect the different aspects more accurately.

Wayland needs this set for the communication pipes, so set a fallback in case it hasn't already been set.

1.7.10.4

This is the reference Wayland compositor.

If the "wayland" DISTRO_FEATURE is present the KMS and Wayland (nested) compositors are enabled.

If the "x11" DISTRO_FEATURE is present the X11 compositor is enabled, and a launcher installed.

This also ships a basic Wayland terminal.

GIT binary patch

From: Alexandru DAMIAN <[email protected]>

If the "wayland" DISTRO_FEATURE is present, enable the Wayland EGL platform. This is required by the reference Wayland compositor, Weston.
