string_list API: document what "sorted" means

The recent work on using string_list to represent the list of refs
that matched with the refs on the other side during fetch heavily
depends on the sort order by string_list's implementation, and
changing string_list will break it.  Document that it uses strcmp()
order, at least for now.

string-list API

The string_list API offers a data structure and functions to handle sorted
and unsorted string lists.
The string_list API offers a data structure and functions to handle
sorted and unsorted string lists. A "sorted" list is one whose
entries are sorted by string value in `strcmp()` order.
The 'string_list' struct used to be called 'path_list', but was renamed
because it is not specific to paths.
