change uid_t, gid_t, and id_t to unsigned types
this change is both to fix one of the remaining type (and thus C++ ABI) mismatches with glibc/LSB and to allow use of the full range of uid and gid values, if so desired. passwd/group access functions were not prepared to deal with unsigned values, so they too have been fixed with this commit.
