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.

+ * 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.
