library/string.m:
Delete long-deprecated substring/3 function and substring/4 predicate.
The newly introduced `string_piece' type has a substring/3 data
constructor which takes (start, end) offsets into the base string,
whereas the function and predicate take (start, count) arguments.
To reduce potential confusion, delete the deprecated function and
predicate.
Delete other deprecated substring predicates and functions as well.
