>Description:
        Fixed critical bug in AxKit::CharsetConv class.
	We had crash of Apache child and multiple errors in log file like
		httpd in free(): error: pointer to wrong page
		httpd in free(): error: pointer to wrong page
		httpd in free(): error: pointer to wrong page
	Updated to AxKit 1.6.2 version.
>How-To-Repeat:
	Just use Apache::AxKit::CharsetConv class
	    {
        	my $encoding = <param:encoding />;
	        my $iconv = Apache::AxKit::CharsetConv->new($encoding,"UTF-8");
	        $query = $iconv->convert($query);
	    }
	On exit from local scope you will have apache child crash and zero length request in browser.
>Fix:
	In file CharsetConv.xs, line 197 changed
	      free(self);
	to
	      Safefree(self);
