This makes it so that the buffers are only allocated once per test instead
of once per transfer. This also removes initial buffer set-up from the
timing window.
Added a new struct into ior.h IOR_io_buffers for the buffer, checkbuffer, and readcheckbuffer
so only one pointer needed to be passed to XferBuffersSetup(), XferBuffersFree(),
and WriteOrRead().
Changed the logic in XferBuffersSetup() and XferBuffersFree() to not be transfer
dependent. If a test includes a write check or read check the checkBuffer
and readcheckBuffer will be created once per test in TestIoSys(). The
argument now taken by both function has changed from the access type to
a pointer to IOR_param_t.
Changed WriteOrRead to take as an additional parameter
the IOR_io_buffers struct, since it was no longer creating those
buffers.
