[svn-r28616] Normalization of H5HL package with revise_chunks.

NOTE: Flush dependency code was not moved.

Tested on:
    Ubuntu 15.10 (Linux 4.2.0 x86_64) gcc 5.2.1 w/ CMake 3.3.2
    serial only (Autotools and CMake since new files were added)
    (these changes have been in revise_chunks for a long time)
