convutils.pm used implicit conversion of undefined value to integer zero. Some of conversion scripts are susceptible to regexp greediness. Fix, avoiding whitespace changes in the output. Also update ICU URLs that moved. No need to back-patch, because the output of these scripts is also in the source tree so we shouldn't need to rerun them on back-branches.
