[svn-r135] ./config/linux

./config/freebsd2.2.1
        Rewritten to be more flexible.

./src/H5AC.c
./src/H5ACprivate.h
./src/H5F.c
./src/H5H.c
./src/H5Gpkg.h
./src/H5Gshad.c
./src/H5O.c
./test/istore.c
./test/tstab.c
        Accumulates cache statistics and displays the results on
        stderr when the file is closed if it was opened with
        H5F_ACC_DEBUG passed into H5F_open()

./src/H5B.c
./src/H5Bprivate.h
./src/H5Fistore.c
./src/H5Gnode.c
        Added more debugging which is turned on if H5B_DEBUG is
        defined on the compile command (see config/linux).

        Fixed a couple of bugs with left insertions which are used by
        the indexed storage stuff.

./src/H5Flow.c
        Fixed a memory leak.

./src/H5Fprivate.h
        Fixed warnings about shifting more than size of object.

./src/H5Fstdio.c
        Fixed seek optimizations back to the way Quincey originally
        had them.

./src/H5V.c
        Removed unused variables.
