Re: patch [big]: fixed Japanese converters

Updated.  Attached patch is against CVS HEAD.

iso2022jp.h:
  Maps for CJK Compatibility Ideographs has been added.

ksx1001.h & ksx1001.c:
  Newly added charsets:
    ISO-2022-KR (RFC1557)
    EUC-KR
    CP949 (a.k.a. UHC or "KS_C_5601-1987")

unicode.c:
  Error handling by unicode_xconvert() breaks string using multibyte
  (e.g. EUC-JP) and/or stateful (e.g. ISO-2022-*) encoding schemes.

  I modified unicode_xconvert() so that it lets converter functions
  handle conversion errors and then (if possible) retry to handle
  errors by itself.  I'm not sure this behaviour is suitable for 
  all implementation of charsets.


New files:
    cjkcompat.pl
    ksx1001.c
    ksx1001.h  (please generate using ksx1001.pl)
    ksx1001.pl
