Both lua-iconv "iconv.open" and the POSIX iconv_open() [1] uses TO,FROM
arguments; I felt keeping the same order was somewhat important.

On the other hand, POSIX iconv() [2] uses INBUF,OUTBUF intermixed with the
buffer sizes. This is a bit inconsistent with the previous one, but not
relevant as there is no way to keep this order in lua-iconv, as the Lua
version returns the converted string.

lua-iconv uses both: open() and new() are aliases to the same function to
preserve, respectively, the name used by POSIX and the usual OOP semantics.
