Adding abillity to add and remove xrefs, refactoring xrefs

[oded-el]

Well, only when I finished this I noticed there's a pull request from January about xrefs.
I don't know what it did not merge, I refactored the xrefs a bit and added the ability to add and remove Xrefs.

Hi, sorry for the late response. I am somewhat busy with other things but will try to get to this PR soon.
In any case, I am a bit worried as it seems to be a breaking API change, and I have no measure of the number of people that will be affected by it.
I am not saying "no", but I need to give the idea of breaking changes consideration, and I have not done that yet.

Hi, is there any progression regarding API change?

Hi,

I have recently decided to start pushing for a new version of Sark, with a focus on IDA 7.x and allowing for breaking API changes.
As you can see, there are currently 2 PRs for xref-editing. I need to compare them and decide on the preferred method. I hope to get to this soon.

Is Sark still maintained? It feels like it's impossible to contribute

Sorry for the huge delay...
I was busy with other things, so didn't have any real attention to maintaining Sark for a while.
This is changing now. The current focus is on testing & migration to IDA 7.4 (dropping backwards compatibility with 6.95).
Once this is done, I'll start considering new features & improvements.
