Introduce a new type, PtrdiffT. Replace lots of uses of OffT (all those
that are memory offsets) with PtrdiffT; OffT should only be used for file
sizes and offsets.
Change Off64T from a ULong to a Long, as it should be. Replace some uses
of ULong in the address space manager with Off64T to match.
Also add a comment explaining the meanings of the basic types like Addr,
OffT, SizeT, etc.
Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an
Int.
