[svn-r12739] Added Direct I/O driver to VFD. It's only supported by SGI Altix (cobalt). There's a configure
option --enable-direct-vfd/--disable-direct-vfd to enable/disable Direct I/O support. The default
is enabled. There's a small test in test/vfd.c. Another way to test it is to set environment
variable HDF5_DRIVER to "direct" and run "make check" in the test/ directory. There'll be some
further improvement in the following checkin including allowing user to provide memory boundary
value, file block size, and copying buffer size.
