Standardize ItemIdData terminology.

Browse Source 
The term "item pointer" should not be used to refer to ItemIdData
variables, since that is needlessly ambiguous.  Only
ItemPointerData/ItemPointer variables should be called item pointers.

To fix, establish the convention that ItemIdData variables should always
be referred to either as "item identifiers" or "line pointers".  The
term "item identifier" already predominates in docs and translatable
messages, and so should be the preferred alternative there.
