Reduce native binary dependencies

[gep13]

@GitTools/developers what are your thoughts on taking this for a spin:

libgit2/libgit2sharp#1618

It would reduce the native dependencies that we currently have, but off the top of my head, I am not sure whether it would "work" for us.

Not in a position to take this for a spin just now, but I thought I would bring it up when it found out about it.

Interesting. If @libgit2 produce a package for it, we can add it and run the tests. As long as all the tests are green, I would give this a huge 👍.

Definitely interesting once available. But probably needs some time until it is available and stable enough for using in GitVersion

GitVersion is already super chatty to git and this would likely slow things down heaps? I think we probably need to move to the in memory model first.

When you say "super chatty", can you give me more details? I see that you do a fetch (unless configured not to) but that's just the one call. I suspect that your fetch will be slower than native code, but if you're only doing the one call, I don't think it will be devastating. (Local repository access is, of course, unchanged.)

So trying a bit of a different approach at solving this problem, I've released a prerelease LibGit2Sharp that should help a bit here. I've updated libgit2 to have built-in support for proxies, so we no longer rely upon libcurl. I think this should help the native dependency problems quite a bit.

This is available in LibGit2Sharp 0.26.0-preview-0070.

Closing, as this was implemented in #1713.
