* Since some types don't have names (e.g. pointer types or anonymous structs or
unions), each type does now also have a unique ID. The global type cache
registers types by ID and by name (if they have one). This fixes clashes of
types with empty names.
* Completely refactored the code dealing with variable values. Formerly we had
Variable and TypeComponentPath to navigate to a component, mapped to a
BVariant representing the value. Now we have:
* Interface Value with various subclasses (BoolValue, IntegerValue, etc.) to
represent a value, with the flexibility for more esoteric values.
* A tree of ValueNode+ValueNodeChild objects to represent the components of a
variable. On top of each ValueNodeChild sits a ValueNode representing the
value of the component, potentially having ValueNodeChild children. This
should allow casting a component value, simply by replacing its ValueNode.
* Interface ValueHandler and various implementations for the different value
types. It is basically a factory for classes allowing to format/display a
value.
* ValueHandlerRoster -- a registry for ValueHandlers, finding the best one
for a given value.
* Interface TypeHandler and various implementions for the different type
kinds (primitive, compound, address, etc.). It is basically a factory for
ValueNodes for that type.
* TypeHandlerRoster -- a registry for TypeHandlers, finding the best one
for a given type.
That's still a bit work in progress. It introduces at least one regression:
The VariablesView doesn't save/restore its state anymore. Will take a while
until that is added back.
