An abstraction which represents a seekable data source.
RandomAccessFile can be trivially mapped to this; in addition, we
can support an adapter for addresses, so we can parse DLLs
directly out of the remote process's address space.  This class is
used by the Windows COFF and Posix ELF implementations. /** An abstraction which represents a seekable data source.
