Currently there are still at least two functions bundled up inside the winsys concept: a) that of a backend resource manager, sometimes capable of performing present() operations, b) the initialization code/routine for the whole driver stack. The inclusion of (b) makes it difficult to share implementations of (a) between different drivers. For instance, a clean xlib winsys could be of use for software-rasterized VG, GLES, EGL, etc, stacks. But that is only true as long as there is no dependency from the winsys to higher level code, as would be the case when we include (b) in this component. This change creates a new gallium/targets subtree, specifically for implementing the glue needed to build individual driver stacks, and moves that code out of a single example winsys, namely xlib. Other drivers continue to build unchanged, but hopefully can migrate to this structure over time.
