Compare two literals with type promotion.
</p>
<p>
The two literals are compared across their range.  If the types
are not the same, they are promoted.  If one is a double or float, the
other is promoted to double, otherwise for integers, otherwise
to strings (all literals have a string value).
</p>
<p>
The comparison returned is as for strcmp, first before second
returns &lt;0.  equal returns 0, and first after second returns &gt;0.
For URIs, the string value is used for the comparsion.
</p>
<p>
flag bits affects comparisons:
  RASQAL_COMPARE_NOCASE: use case independent string comparisons
  RASQAL_COMPARE_XQUERY: use XQuery comparison and type promotion rules
  RASQAL_COMPARE_RDF: use RDF term comparison
  RASQAL_COMPARE_URI: allow comparison of URIs (typically for SPARQL ORDER)
