[svn-r134] Changes since 19971023

----------------------

./config/conclude.in
        Test work when `.' isn't in $PATH.

./src/H5F.c
./src/H5Fcore.c         NEW
./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fstdio.c
./src/Makefile.in
./MANIFEST
        Added the in-core temporary file driver as an exercise to
        clean up some of the H5F package.  It speeds up `testhdf5 -o
        stab' by 25 percent!  If you want to try it you'll need to
        recompile everything with `-DH5F_LOW_DFLT=H5F_LOW_CORE'.
        Don't expect testhdf5 to ever work since creating a file,
        closing it, and then opening it for read-only will fail.
