* include/ruby/oniguruma.h: remove ONIG_ENCODING_* and OnigEncoding*
which are not builtin. * regenc.{c,h} (onigenc_mb2_code_to_mbclen, onigenc_mb4_code_to_mbclen): fix prototype. * enc/big5.c, enc/euc_kr.c, enc/euc_tw.c, enc/gb18030.c, enc/koi8_r.c, enc/windows_1251.c: imported from Oniguruma. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@15026 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
