[svn-r5130] Purpose:
    Bug Fix & Feature

Description:
    The selection offset was being ignored for optimized hyperslab selection
    I/O operations.

    Additionally, I've found that the restrictions on optimized selection
    I/O operations were too strict and found a way to allow more hyperslabs
    to use the optimized I/O routines.

Solution:
    Incorporate the selection offset into the selection location when performing
    optimized I/O operations.

    Allow optimized I/O on any single hyperslab selection and also allow
    hyperslab operations on chunked datasets.

Platforms tested:
    FreeBSD 4.5 (sleipnir)
