An old esurface should be destroyed and set to be NULL when doing
un-tab and re-tab so that a new esurface an context can be created
for the window widget that those will be bound to.

Fails to build on windows (probably also on --disable-opengl builds). take care, Gerd
An old esurface should be destroyed and set to be NULL when doing
un-tab and re-tab so that a new esurface an context can be created
for the window widget that those will be bound to.

If guest fb is backed by dmabuf (blob-resource), the texture bound to the
old context needs to be recreated in case the egl is re-initialized (e.g.
new window for vc is created in case of detaching/reattaching of the tab)
v2: call egl_dmabuf_release_texutre instead of putting 0 to dmabuf->texture
