package/opengl/libgbm: new virtual package Since 18.0-Leia, Kodi implements stand-alone gbm support alongside x11 & wayland. To enable building libgbm in mesa3d without x11 & wayland we need to create a virtual package for libgbm. Also other packages besides mesa3d may provide libgbm.so, see http://patchwork.ozlabs.org/patch/647235/ http://patchwork.ozlabs.org/patch/939703/ It turns out that libgbm has seen several additions in its API over time, and therefore not all libgbm implementations provide support for all features. In order to account for this, this commit adds two hidden boolean options that allow libgbm providers to indicate which optional features they support: BR2_PACKAGE_LIBGBM_HAS_FEATURE_FORMAT_MODIFIER_PLANE_COUNT and BR2_PACKAGE_LIBGBM_HAS_FEATURE_DMA_BUF. These booleans must be selected by the packages providing libgbm implementations, and depended on by packages using libgbm.
