Fix kiconv on the 64bit plathomes.

- Correct idxp pointer to point the properly address of the
each array of the kiconv character conversion tables,
so that character conversion work properly when file
systems are mounted with kiconv options.

- The definition of ICONV_CSMAXDATALEN was also bogus
because it was defined as if all machines were 32bit
computers.
