testpar/t_2Gio.c: Fix a typo that I think was introduced by a

        previous warnings PR.  An array element was assigned to
        itself---shape[2]Â =Â shape[2];---instead of being assigned to
        chunk[2].

fortran/src/H5Pf.c: move conditional compilation controlled by
        H5_NO_DEPRECATED_SYMBOLS outside of a function for readability.

fortran/src/H5match_types.c: put a variable's declaration under the same
        conditional compilation (H5_FORTRAN_HAVE_C_LONG_DOUBLE) as its
        use.

For now, skip compilation of some unused debug dump routines in the JNI.
While I'm in the JNI, delete a set-but-unused variable.

src/H5Z.c: condition a variable declaration on H5_NO_DEPRECATED_SYMBOLS
        so that it's not declared but unused or vice versa.

test/cache_common.h: add an #include in to get some symbols we need to
        avoid implicit declaration warnings.

test/dsets.c: use a more conventional conditional-compilation syntax.

test/dt_arith.c, test/fillval.c: initialize a bunch of uninitialized
        variables before use.

test/vfd.c: pass the expected type of `void **` to posix_memalign(3)
        instead of `int **`.

testpar/t_bigio.c: explicitly compare with 0 instead of using ! when
        "equal to 0?" is the question not "is false?"  Repair some
        indentation while I'm here.

testpar/testpar.h: repair misaligned line-continuation backslashes in a
        macro that probably should be a function so that we don't have
        to fiddle with the line continuation to begin with.

tools/src/h5repack/h5repack_main.c: fix some compiler fussing about
        enums.

tools/test/perform/pio_engine.c: the compiler fusses if you cast a
        function call returning double directly to off_t.  It's ok if
        you cast a variable that's a double to off_t, however.  Write
        and use a new function, sqrto(), to avoid the cast warnings.
