in connection with Smob allocation
https://code.google.com/p/lilypond/issues/detail?id=4293

Since this is almost only my turf and the changes are rather  
straightforward and test as harmlessly and this makes Guilev2 progress,  
pushed to staging as

    Issue 4293/3: smobs.tcc: robustify {mark,print}_trampoline in  
connection with free_smob

    Guilev2 has little qualms calling mark/print even after freeing a smob.
    So we clean out the pointer to smob data when freeing/unregistering it,
    and let the mark/print trampolines detect this condition and punt.

    Issue 4293/2: Remove Music_function::mark_smob with  
ASSERT_LIVE_IS_ALLOWED

    GUILEv2's garbage collection is too asynchronous to make this work.
