    iconv: Sync#2 - Support ICONV_{GET,SET}_ILSEQ_INVALID
    
    Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns EILSEQ
    when there is an invalid character in the output codeset while it is
    valid in the input.  However, POSIX requires iconv() to perform an
    implementation-defined conversion on the character.  So, Citrus iconv
    converts such a character to a special character which means it is
    invalid in the output codeset.
    
    This is not a problem in most cases but some software like libxml2
    depends on GNU's behavior to determine if a character is output as-is
    or another form such as a character entity (&#NNN;).
