RFR 8047765: Generate blacklist.certs in build

[Wang Weijun]

Hi All

Please review the fix at

   http://cr.openjdk.java.net/~weijun/8047765/webrev.00/

where the generation of blacklisted.certs is moved from developer-manual to build-auto. I copied the mechanisms from GENDATA_HTML32DTD.

One thing I am not sure about is that if I update the tool a little, all tools are rebuilt and all gendata files are regenerated. Is this expected?

Thanks
Max
