[xml] patch for warning on solaris

[Graham Bennett <graham-libxml simulcra org>]

Hi all,

I noticed a compilation warning coming from encoding.c, which happens
because the native (not GNU) iconv on solaris (sensibly) takes a const char **
rather than a char ** as input.

Here's a patch, but it's not complete as you'd need to check that solaris 
iconv is being used, not just that the platform is solaris.

+#endif
     if (in != NULL) {
         *inlen -= icv_inlen;

PS - does anyone know why GNU iconv has the input as a pointer to
pointer to non-const char?

cheers,

Graham.
