(widechar<->char, widechar<>*string), based on patch from
Rimgaudas Laucius (mantis #7758)
* no longer perform compile-time widechar/string->char/ansi/
shortstring conversions if they would destroy information
(they can't cope with widechars with ord>=128). This means
that you can now properly constant widechars/widestrings
in source code with a {$codepage } set without risking that
the compiler will mangle everything afterwards
* support ESysEINVAL return code from iconv (happens if last
multibyte char is incomplete)
* fixed writing of widechars (were converted to char -> lost
information)
