* 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
* Fall 2014
