[svn-r8613] Purpose:

    Refactor code

Description:
    Move chunk and contiguous cached raw data from file information to dataset
information.  This simplifies a number of internal interfaces, aligns the
code with it's purpose better and should allow more optimizations to the
chunked data I/O performance.

Platforms tested:
    Solaris 2.7 (arabica)
    FreeBSD 4.10 (sleipnir)
    h5committest
