Rewrite the perl scripts to produce our Unicode conversion tables.
Generate EUC_CN mappings from gb-18030-2000.xml, because GB2312.TXT is nolonger available.Get UHC from windows-949-2000.xml, it's more up-to-date.Plus tons more small changes. With these changes, the perl scriptsfaithfully produce the *.map files we have in the repository, from theexternal source files.In the passing, fix the Makefile to also download CP932.TXT and CP950.TXT.Based on patches by Kyotaro Horiguchi, reviewed by Daniel Gustafsson.Discussion:https://postgr.es/m/08e7892a-d55c-eefe-76e6-7910bc8dd1f3@iki.fi
