Merging in latest from upstream (HDFFV/hdf5:refs/heads/develop)

* commit 'ab3963b28e59419f8e857ec224dd4efa3ea6dd8e': (214 commits)
  Merge SWMR-related testing to existing tests.
  Bring over tweak for missing environment variable.
  Update CMake configuration files with SWMR accumulator changes.
  Add missing accumulator test.
  Merge SWMR-oriented accumulator tests from revise_chunks to develop.
  Bring Java SWMR changes from revise_chunks to develop branch
  Snapshot version 1.9 release 235
  Change dlopen from RTLD_NOW to RTLD_LAZY
  Fix bad implementation of Windows nanosleep equivalent.
  Removed NDEBUG guards from H5AC test functions.
  Bring SWMR-related tools changes from revise_chunks to develop.
  Bring over changes from revise_chunks that cleanup recent SWMR changes from code review feedback.
  Updated the H5FS cache code to grab the correct tag and modified the freespace test to use dxpls that have been tagged with the H5AC__FREESPACE_TAG global tag instead of H5AC_ind_read_dxpl_id. The library code now expects the owner of the free space manager to tag it so the owner-less free space managers in the freespace tag had to be tagged with *something* to avoid cache errors.
  Updated the comment for the valgrind fix.
  Fixed a valgrind problem in file shutdown exposed by the swmr.c test.
  Reduce timeout as normal run time on windows is less then 10 min
  Updated the icc flags (C flags only).
  Another Java oversight (sorry, don't have Java configured on my Mac)
  Correct oversight in Java test and remove direct VFD from SWMR supported drivers.
  Bring SWMR support in to the main development branch.  (Finally!)  More tests and the tool and API wrappers will be coming in over the weekend.
