string-list: add string_list initializer helper function
The string-list API has STRING_LIST_INIT_* macros to be used to define variables with initializers, but lacks functions to initialize an uninitialized piece of memory to be used as a string-list at the run-time. Introduce `string_list_init()` function for that. Signed-off-by: Tanay Abhra <tanayabh@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
