firestring_estr_xml_encode - encode an estring into another estring for
transmission inside XML data
int firestring_estr_xml_encode(struct firestring_estr_t *destination,
struct firestring_estr_t *source)
firestring_estr_xml_encode() encodes the contents of source by escaping
characters that might trigger XML processing into destination, provided
that there is room in destination. The minimum required space in
destination is the length of source * 6.
0 if the string was encoded successfully; 1 if there was insufficient
space in destination for the encoding to occur.
