6.04d: 2011-12-14

• Prefetcher refactored so that the semantics is clearer. Functionality stays the same.
• Fixed bugs in prefetcher.
• Fixed memory leak in prefetcher.
• Must not invalidate buffer in 'half closed' mode.
• BlockRead was not functioning properly when called at the end of file (when previous call to BlockRead already returned less data than requested) if
  buffered mode was used.
• [Istvan] TGpHugeFile.Fetch didn't decrement hfBufSize when reading from buffer. bufp was incremented by requested (read) amount instead of actually read (trans) amount
• TGpHugeFile.Fetch did not always set block size when block was read from prefetcher.
