xnest: wrap the xnest cursor sprite funcs around the mi funcs.

Modelled after the xfree86 code. Call miDCInitialize to init the SW rendering
engine, then take the pointers, store it in a xnest-local variable, and put
the xnest-specific sprite funcs in place. In the xnest sprite funcs, call
through to the mi sprite funcs after doing xnest-specific stuff.
