xml: use ANSI types and struct initialization

long is atleast 32-bits, codepointtoutf8() works with >= 32-bit types. Valid
codepoint ranges are not larger than this. unsigned char is not needed because
converted unicode bytes don't use this range.

tested all valid codepoints and output on amd64, i386 and SPARC64.
