style: decouple different uses of item_number

Browse Source 
item_number is used for elements of ritem as well as indices into
ritem which is fairly confusing.  Introduce item_index to represent
indices into ritem.

* src/gram.h (item_index): Introduce it for ritem indices.
* src/closure.h, src/closure.c, src/ielr.c, src/lr0.c,
* src/print-graph.c, src/state.h, src/state.h:
Replace uses of item_number with item_index where appropriate.
