Configuration:
-------------
+ - Added new configure option to support building parallel tools.
+ See Tools below (autotools - CMake):
+ --enable-parallel-tools HDF5_BUILD_PARALLEL_TOOLS

- Added new configure options to enable dimension scales APIs (H5DS*) to
use new object references with the native VOL connector (aka native HDF5
library). New references are always used for non-native terminal VOL

Tools:
------
+ - Added a new (unix ONLY) parallel meta tool 'h5dwalk', which utilizes the
+ mpifileutils (https://hpc.github.io/mpifileutils) open source utility
+ library to enable parallel execution of other HDF5 tools.
+ This approach can greatly enhance the serial hdf5 tool performance over large
+ collections of files by utilizing MPI parallelism to distribute an application
+ load over many independent MPI ranks and files.
+
+ An introduction to the mpifileutils library and initial 'User Guide' for
+ the new 'h5dwalk" tool can be found at:
+ https://github.com/HDFGroup/hdf5doc/tree/master/RFCs/HDF5/tools/parallel_tools

- Refactored the perform tools and removed depends on test library.
Moved the perf and h5perf tools from tools/test/perform to
