set CHANGE make ly_set* functions return LY_ERR values
unify ly_set* function that were returning -1 as error indicator
combined with positive value indicating index inside the set. The most
of other libyang functions return LY_ERR to indicate result. The problem
of these functions was also the limited range of the returned index.
While internally index is uint32_t, it was limited only to a positive
part of int type.
