Merge pull request #183 in HDFFV/hdf5 from ~KOZIOL/hdf5:develop_swmr_merge to develop

Merged the final library SWMR changes from revise_chunks.

* commit '15e04901a0cea65b2b0fa3ca869341a2b656bfdf':
  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.
  Add some Java methods that were missed earlier.
  Minor normalization cleanups.

+ * Function:	H5FD_supports_swmr_test()
+ *
+ * Purpose:	    Determines if a VFD supports SWMR.
+ *
+ *              The function determines SWMR support by inspecting the
+ *              HDF5_DRIVER environment variable, not by checking the
+ *              VFD feature flags (which do not exist until the driver
+ *              is instantiated).
+ *
+ *              See test/Makefile.am for a list of the VFD strings.
+ *
+ *              This function is only intended for use in the test code.
+ *
+ * Return:	    TRUE (1) if the VFD supports SWMR I/O or vfd_name is
+ *              NULL or the empty string (which implies the default VFD).
+ *
+ *              FALSE (0) if it does not
+ *
+ *              This function cannot fail at this time so there is no
+ *              error return value.
