Distinguish signed, float in type descriptor

Browse source 
* Add a flag to indicate signed integral values and one to indicate
  floating-point values
* Set these flags in the output of idlc
* Use them when printing sample contents to the trace

By encoding the information as flags in reserved bits the actual
serialization and deserialization is unaffected.
