Purpose: Fix bug HDFFR-9920 cont.

Description:
    Adding user's test revealed a flaw in the fix.
    Moved CommonFG's functions in Group to H5Location, so that they
    could be called by objects that can be used to specify a location
    Also, rearranged many "#include" header files to resolve conflicts.

Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 (platypus)
    Darwin (osx1010test)

-// - getLocId is called by all functions, that call a C API, to get
-//   the location id, which can be either a file id or a group id.
-//   This function is pure virtual and it's up to H5File and Group
-//   to call the right getId() - although, as the structure of the

-//   ***Updated: after the classes are rearranged (HDFFV-9920), functions

-//		 instead of getLocId().  getLocId() is kept for backward

-//   GroupIException.
-//   ***Updated: after HDFFV-9920, methods in class Group use throwException

+// From H5CommonFG.cpp
+// Notes with "***Updated" are new and for Group.cpp
+// Original notes are from December 2000
+//
+// There are a few comments that are common to most of the functions
+// defined in this file so they are listed here.
+// - getLocId is called by all functions, that call a C API, to get
+//   the location id, which can be either a file id or a group id.
+//   This function is pure virtual and it's up to H5File and Group
+//   to call the right getId() - although, as the structure of the
+//   library at this time, getId() is basically the IdComponent::getId()
+//   ***Updated: after the classes are rearranged (HDFFV-9920), functions
+//		 in CommonFG are moved to Group, and they can call getId()
+//		 instead of getLocId().  getLocId() is kept for backward
+//		 compatibility on user applications.  Aug 18, 2016 -BMR
+//   ***Updated: Moving to Group was a mistake, now to H5Location
+//		 Aug 24, 2016 -BMR
+// - when a failure returned by the C API, the functions will call
+//   throwException, which is a pure virtual function and is implemented
+//   by H5File to throw a FileIException and by Group to throw a
+//   GroupIException.
+//   ***Updated: after HDFFV-9920, methods in classes H5Location and Group
+//   use throwException to distinguish the FileIException and GroupIException.
+//   CommonFG is no longer used in the library.  Aug 18, 2016 -BMR
+//   ***Note: following the changes in HDFFV-9920, some of the methods could
+//   throw different exceptions, but for backward-compatibility, throwException
+//   is kept in those methods as well. Sep 17, 2016 -BMR
