Clean up the usage of the table API. There have always been enough

routines in alloc.h to treat table as an opaque type, however even we
got lazy at times and didn't do the right thing.  This change causes
compile time errors for folks who aren't treating table as an opaque type.
It was built as part of my table hashing patch, but the hashing has all
been removed (since it didn't appear to be a win).
