 * 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.

 * Programmer:	Dana Robinson
