* picked from old libgstegl: - GstEGLImageMemory - GstEGLImageAllocator - last_buffer management from removed GstEGLImageBufferPool * add-ons: - GstEGLImageMemory now old a reference on GstGLContext so that it can delete the EGLImage and its gltexture source while having the associated gl context being current. - add EGLImage support for GstVideoGLTextureUploadMeta which mainly call EGLImageTargetTexture2D - GstGLBufferPool now supports GstEGLImageAllocator - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator to upstream https://bugzilla.gnome.org/show_bug.cgi?id=703343
