[svn-r22209] Purpose: Fixed bugs HDFFV-2761 & HDFFV-7852
Description:
- Replaced PredType::NotAtexit() with PredType::AtExit(H5CPP_EXITED)
and used PredType::AtExit as a flag to detect when all predefined
types have been destroyed. Then, H5close will be called to terminate
the library after its being re-initiated when the PredType destructors
were activated. This change removed the memory leaks shown by the
user's sample program in HDFFV-2761.
- Added H5CPP_EXITED for PredType::AtExit to use as a flag
- Rearranged constructors in CompType to fix bug HDFFV-7852
- Updated some inaccurate comments
- Removed stream functions from FileAccPropList
- Replaced H5_VMS with appropriate macro in H5IdComponent.cpp
Platforms tested:
Linux/32 2.6 (jam)
Linux/64 2.6 (amani)
SunOS 5.10 (linew)
