From: Tomi Ollila <tomi.ollila at iki.fi>

The function notmuch_talloc_g_key_file_get_string_list() wraps
call to g_key_file_get_string_list() in a way that the returned
string array is copied to talloc'd memory area. The returned
pointer is itself also a talloc context, child of the context
given as first argument.
