add core engine of Citrus iconv and some support routines. - iconv core (citrus_iconv) - coded character set mapper (csmapper) - encoding scheme database (esdb) - standard encoding scheme handler (stdenc) - basic character set manipulation utilities (bcs) - mmap based infrastructure (citrus_lookup/_mmap/_memstream/_db) - some source codes of new plugins (not built yet)
