[PATCH] test-string-list.c: Fix some sparse warnings

[Ramsay Jones <ramsay@xxxxxxxxxxxxxxxxxxx>]

In particular, sparse complains as follows:

        SP test-string-list.c
    test-string-list.c:10:6: warning: symbol 'parse_string_list' was not \
        declared. Should it be static?
    test-string-list.c:18:6: warning: symbol 'write_list' was not \
        declared. Should it be static?
    test-string-list.c:25:6: warning: symbol 'write_list_compact' was not \
        declared. Should it be static?
    test-string-list.c:38:5: warning: symbol 'prefix_cb' was not \
        declared. Should it be static?

In order to suppress the warnings, since the above symbols do not
need more than file scope, we simply include the static modifier
in their declaration.

Hi Michael,

If you need to re-roll your 'mh/string-list' branch, could you
please squash the relevent parts of this patch into those commits.

Thanks!

ATB,
Ramsay Jones
