Refactoring about Link Format

[sbernard31]

This is a refactoring to try to propose a API to bound Attribute and Link world, proposing a kind of LWM2M flavored Link.
Some idea are described at :

• Make LinkParser extensible. #1118 (comment)
• Make LinkParser extensible. #1118 (comment)

This is an huge PR ... I really don't like to do that 😞...
However I tried to make it with a series of "small" consistent commit.

I will probably squash all of this in 1 commit when integrating this in master.

There are renaming work but I think this should be done in some other PRs :
- Use LwM2mLink for discover
- Use Version instead of String for VERSION.
- Add notification/properties kind to model.
- Add range check
- Add applicability check
- quoted version invalid by default ?
- Make linkparser/attribute parser configurable.
Finally done in this PR.

@sbernard31 unfortunately I have limited time recently, so I can't look at this. I believe all the changes are OK 😄

I think this is in a mergeable state.
I plan to integrate it in master on next Monday.

This is now integrated in master (commit 30f79d3)

Noob here, noob to Java and everything. Somehow many stuff mentioned here is not available to the Leshan-Server-Demo. For example:

org.eclipse.leshan.core.link.attributes does not exist.
package org.eclipse.leshan.core.link.lwm2m.attributes does not exist

I tried clean installing.

Can somebody help me here?

When I go into details, checking out the external libraries. I do not see these files are available as it does in Master. Somehow the Maven builds are not new. If that's the case, how do I build jar directly from the master and use them in the demo server?

Which version are you talking about ? (where/how do you get your "leshan-server-demo" ?

Currently there is no (stable or milestone) release which integrate this. This is available in master.
To build from master : https://github.com/eclipse/leshan#compile-leshan--run-demos

You can also download the already built jar of master looking at the https://github.com/eclipse/leshan#readme table (leshan v2.0.x)
