git_clone_into no longer exists

[mduggan]

Trying to use pygit2 against the current head libgit2 fails because git_clone_into has been removed from the public API.

I'd submit a pull request, but I'm not sure what the correct "fix" is. Is it just to completely remove the clone_into function and corresponding definition in decl.h?

pygit2 works against the released versions of libgit2. There is no
branch which tracks the next release, so there's nowhere to put such a
fix. Not that there can't be, but such a branch would be out of date
very quickly and there's not really the manpower in this project to keep
such a branch.

As for the fix itself, the functionality that git_clone_into provided
has been moved into the repository and remote factory callbacks in the
git_clone options.

No problem, it doesn't really bother me, just thought I'd report. I was debugging issue #403 and thought it might be better to update to the latest libgit2 first, but apparently not :)

libgit2 v0.22 has been released, and we now support this version.
