Runtime tables deterministic ordering (4)

Browse source 
Output C/C++ type strings (| separated) in swig_type_info tables in
fixed order. The types are output in alphabetically sorted order,
with an exception. The final type is a fully resolved type, but
does not necessarily include default template parameters.
This type is the one used by SWIG_TypePrettyName which is commonly
used to display a type when the wrong type is passed in as a
parameter.

Previously the order was not very deterministic due to the use of
internal hash tables which do not have an ordering guarantee.
