st/dri: Reshuffle files and make it obvious which files are shared

In short:
git mv ../drisw/Makefile dri/sw
git mv drisw.[c|h] sw
git mv dri2.[c|h] dri1.[c|h] Makefile drm
git rm ../drisw
ln -s <common files> drm/*

-/* TODO:
- *
- * stride:
- *
- * The driver and the loaders (libGL, xserver/glx) compute the stride from the
- * width independently. winsys has a workaround that works for softpipe but may
- * explode for other drivers or platforms, rendering- or performance-wise.
- * Solving this issue properly requires extending the DRISW loader extension,
- * in order to make the stride available to the putImage callback.
- *
- * drisw_api:
- *
- * Define drisw_api similarly to dri_api and use it to call the loader. This is
- * predicated on support for calling the loader from the winsys, which has to
- * grow for DRI2 as well.
- *
- * xshm:
- *
- * Allow the loaders to use the XSHM extension. It probably requires callbacks
- * for createImage/destroyImage similar to DRI2 getBuffers. Probably not worth
- * it, given the scope of DRISW, unless it falls naturally from properly
- * solving the above two issues.
- *
- * swrast_create_screen:
- *
- * Allow for any software renderer to be used. Factor out the code from
- * targets/libgl-xlib/xlib.c, put it in targets/common or winsys/sw/common and
- * use it in all software targets.
