Mark ItemPointer arguments as const throughout

Browse Source 
This is a follow up 991295f.  I searched over src/ and made all
ItemPointer arguments as const as much as possible.

Note: We cut out from the original patch the pieces that would have
created incompatibilities in the index or table AM APIs.  Those could
be considered separately.
