[svn-r4914] Purpose:

    Bug fix & feature add
Description:
    Added new API function H5Sget_select_type to determine type of selection in
    a dataspace.  Return values are defined by the H5S_sel_type enumerated type
    in H5Spublic.h

    Also, hyperslab operations involving a "all" or "none" selection are not
    generating the correct resulting selections.

Solution:
    Added more code to make hyperslab operations against an "all" or "none"
    selection generate the correct results.

Platforms tested:
    FreeBSD 4.5 (sleipnir)
