[svn-r14326] Description:

    - Keep skip list for tracking chunks with dataset (instead of creating/
        destroying it for each I/O operation) and just delete the skip list
        nodes.
    - Avoid computations for normalizing selection offset when offset not set.
    - Avoid updating object modification time twice during dataset creation.
    - Avoid updating dataset layout message (and object modification time)
        until dataset is closed.

Tested on:
        FreeBSD/32 6.2 (duty) in debug mode
        FreeBSD/64 6.2 (liberty) w/C++ & FORTRAN, in debug mode
        Linux/32 2.6 (kagiso) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe,
                                in debug mode
        Linux/64-amd64 2.6 (smirom) w/default API=1.6.x, w/C++ & FORTRAN,
                                in production mode
        Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
                                in production mode
        Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
                                w/szip filter, in production mode
        Mac OS X/32 10.4.10 (amazon) in debug mode
