Purpose: Improvement for HDFFV-10004

Description:
    When adding wrappers for H5Lexists, a new class, LinkAccPropList, was
    added to the C++ API, triggered complicated circular dependencies.  Thus,
    some improvement was made to resolve the problems.
    - Replaced existing functions openXxxType with individual type constructors
      + Added individual XxxType constructors to replace the existing functions
        openXxxType because it's rather awkward to use these functions.
      + Moved openXxxType from H5Location back to CommonFG
      + Put back CommonFG as a baseclass of Group for openXxxType functions.
      + This replacement should improve usability and prevent the problem of
        circular dependencies.
    - Removed overloaded constructor that takes an Attribute when there is
        already one that takes H5Location because Attribute inherits from
        H5Location now.
Platforms tested:
    Linux/32 2.6 (jam)
    Darwin (osx1010test)
    Linux/64 (platypus)
