Rework data_type parsing to bring integer vectors into data_type_t method.
...
This adds the vector_type_t and real_type_t types to handle
vector and real types in tf_port items. This cleans up a lot
of the parsing for these items.

Update __vpiNamedEvent to remove struct and remove extra class statements
...
The clang compiler does not like using struct to reference a class object.
This patch removes all the struct keywords for __vpiNamedEvent objects
since they are now a class and can be called without a struct/class
qualifier.
This patch also removes all the extra class qualifiers from the rest of
the source code.

Implement simple typedefs, and parse type identifiers.

This gets me to the point where the parser stashes a defined type,

IDENTIFIER and TYPE_IDENTIFIER.

Filter callbacks of value changes to array words.

When looking for a value change on a part select of an array word,
the callback handle has to save the current value and test it with
the new value to see if there is an actual change. If not, then
suppress the callback.
