Update to Tycho 4.0.8-SNAPSHOT to process update.id advice

[merks]

All the update.id advice was commented because Tycho 4.0.7 throws exception; this re-enables all those. Also, each p2.inf for each product is renamed to epp.p2.inf which avoids a related bug parsing the advice file for the project as a whole as opposed to parse the product-specific advice. Define a file association in the setup so it's easy to open an eep.p2.inf with the properties editor.

I have manually verified that the update advice ranges are processed both for the features and the products:

I removed the advice from the embedcpp product because there is no neon version of that product.

I even wonder are these needed for any product ? Update of a 8 years old product will most likely fail for many other reasons too.
