Add axi master

[DavidMartinPhios]

Added axi master with equally powerful implementation as axi lite master has

Thanks for getting this started. I'm aware of several implementations over the years but non of them made it to open source. It so happens that I have my eyes on yet another implementation in progress that may or not make it to the public. Even if that doesn't become open source, I can keep track of what features it requires such that the VC released by VUnit can meet those as well.

I will get back when I have more info.

As you might figured out already this implementation is not yet finished. I am still working on it. Basically I am now adding the functionallity to each single signal. At the moment I have deticated reserved time to implement this specific VC. It would be nice to know if the work will get obsolete some day or be replaced by another implementation. Otherwise I will keep going with the implementation. Hopefully with your early review / support.

@LarsAsplund
Do you think that it is necessary to move the signals id, last, etc. to the bus_master record or is it ok to implement them around on a higher level as it is right now?

[LarsAsplund]

Since you've started and the other implementation may not make it to open source, I think we should continue on what you have. What I hope is to align on the required feature set such that you both can work on the open implementation in the end. I will come back and review a bit later,

Thank you for the answer! I am currently working on the read burst behaviour. It is not finished yet but I think you could get an idea where the journey should go.

@LarsAsplund
Do you already had the change to review the axi master? At the moment a very basic version is implemented but it should provide basic read and write possibilities for burst and none burst.

[LarsAsplund]

I have yet to review it. The other implementation I'm keeping my eyes on is settling now so I think I will be in a position to review shortly and then make sure that the one you have is "feature compatible". With that I don't mean that it has to have all features but rather that the API is such that it can evolve and eventually cover all the things the other project is requiring. That way there is a chance that the two efforts can be merged in the end.

@LarsAsplund
I will wait for your review before I continue further implementations. Just to be sure that it is not completely running in the wrong direction.

@DavidMartinPhios Please have a look at the updated standard rules. Rule 7 and 12 will make more sense when I have pushed supporting code but if you follow the rest of them you will have most of the work done. Compared to the previous draft standard, the rules have been updated to make better use of the identity package, VUnit events and packages.

@LarsAsplund What is the sync interface mentioned by rule 9? Do I have to make some changes to my entity? If yes, could you please give me more information about what I have to change / implement?
