Simplify tape block format.
No more indirect blocks. The blocks form a linked list instead.
This saves some memory, because we don't need to have a buffer in memory to
hold the indirect block (or blocks). To reflect that, TAPE_BUFFER_OVERHEAD
is reduced from 3 to 1 buffer, which allows using more memory for building
the initial runs.
