[PATCH 0/3] virgl: enable in qemu when 'opengl' is in DISTRO_FEATURES

["Alexander Kanavin" <alex.kanavin@gmail.com>]

virgl is a virtualized accelerated 3D graphics support for the qemu
guests. This patchset enables virgl in qemu, when 'opengl' is in
DISTRO_FEATURES. Virgl is entirely opt-in (via non-default options
to 'runqemu'). By default qemu behaves exactly as before, and does
not use virgl.

This adds a few native dependencies to qemu-system-native
(particularly, libdrm, virglrenderer and a special minimal configuration
of mesa-native). I tested the impact on build times: it is about 20
seconds on a 32 core machine. 'bitbake core-image-minimal' goes from
22m23s to 22m44s.

The following changes since commit f9e11276432f1903047f483a68ca4b5a0d6c6111:
