xmlparser: fix token buffer being too small

What this patch does is replace the token buffer of static size in
xml_parser_get_node with a malloced buffer. If the lexer notices, that it
needs more size it just increases the size of this buffer by factor two and
tries again. This may not be very elegant, but it works.

node_name and property_name are dynamically-sized too.
