Unified interface for attributes

In this MR, I propose a more unified attributes handling.

This MR, once merged, will break every other MR!

Refactor

• Use the term "attribute" instead of "parameter"
• Uniformized function naming ("hasAttr" and "getAttr" + "addAttr"/"setAttr"/"delAttr" for DynamicAttributes)
• Parametrizable -> StaticAttributes
• CParameter -> DynamicAttributes
• Adding abstract class Attributes to uniformize Dynamic & StaticAttributes

Also

• Includes fix for bug #8 (closed) (as it may get lost in MR !9 (merged))
• Distinguish between "addAttr" (asserts if already exists) and "setAttr" (do not care if already exists)
• "Universal" Python binding for DynamicAttributes
• Added AIDGE_THROW_OR_ABORT macro
