Purpose: Fixed HDFFV-4259
Description:
    - Used H5I_INVALID_HID instead of 0 to initialized member "id" in classes
      that represent HDF5 objects.  For PropList, H5P_DEFAULT has to be used
      instead of H5I_INVALID_HID.
    - Added try/catch block to some dynamically allocating memory code and
      re-throw the bad_alloc exception with a message informing the location of
      the failure.
Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
Purpose: Fixed HDFFV-8928
Description:
    Followed hints on the JIRA issue to remove several potential memory
    leaks.
Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
Description:
    Removed the try/block with new/bad_alloc that were unintentionally
    committed previously.
Platforms tested:
    Linux/ppc64 (ostrich)
    Linux/32 2.6 (jam)
    SunOS 5.11 (emu)
Fix missing endif
Fix for: HDFFV-8715
HDF5_PARAPREFIX is ignored in parallel dense attribute and performance tests.

tested on Jam w/ parallel.
Bug fix: HDFFV-8933

Description:
Mac has changed to use the clang/clang++ compilers but compiler settings for production, debug and profile
were not setup.

Solution:
Setup default values for PROD_CFLAGS, PROD_CPPFLAGS, DEBUG_CFLAGS, DEBUG_CPPFLAGS.
PROFILE_CFLAGS and PROFILE_CPPFLAGS were set too but clang does not -pg or such for
profiling. Need to fix it later.

Tested: duck, swallow, and quail using --enable-production.
Purpose: Fixed HDFFV-8922
Description:
    Added notes regarding UTF-8 and extended ASCII, provided in HDFFV-8899,
    to C++ API.
Platforms tested:
    Linux/32 2.6 (jam) - only in comments
fix filename generation with prefix for perf test.

tested h5commitest, jam & platypus parallel.
Update the default setting for the memb_addr array when use passes NULL to equally divide all the address space between all the members.
Before there was one chunk of the address space not being used.

tested h5committest, and multi vfd make check on jam.
- fix core driver eof initialization.
- merge from trunk.
- fix expected output for multi VFD h5extend tests after merging in
the change for multi vfd memb addr settings from trunk.
