DRI interface changes and DRI2 direct rendering support.
Add DRI2 direct rendering support to libGL and add DRI2 client side protocol code. Extend the GLX 1.3 create drawable functions in glx_pbuffer.c to call into the DRI driver when possible. Introduce __DRIconfig, opaque struct that represents a DRI driver configuration. Get's rid of the open coded __GLcontextModes in the DRI driver interface and the context modes create and destroy functions that the loader was requires to provide. glcore.h is no longer part of the DRI driver interface. The DRI config is GL binding agnostic, that is, not specific to GLX, EGL or other bindings. The core API is now also an extension, and the driver exports a list of extensions as the symbol __driDriverExtensions, which the loader must dlsym() for. The list of extension will always include the DRI core extension, which allows creating and manipulating DRI screens, drawables and contexts. The DRI legacy extension, when available, provides alternative entry points for creating the DRI objects that work with the XF86DRI infrastructure. Change DRI2 client code to not use drm drawables or contexts. We never used drm_drawable_t's and the only use for drm_context_t was as a unique identifier when taking the lock. We now just allocate a unique lock ID out of the DRILock sarea block. Once we get rid of the lock entirely, we can drop this hack. Change the interface between dri_util.c and the drivers, so that the drivers now export the DriverAPI struct as driDriverAPI instead of the InitScreen entry point. This lets us avoid dlsym()'ing for the DRI2 init screen function to see if DRI2 is supported by the driver.
