[RFE] rebase routines

[ignatenkobrain]

libgit2 supports rebasing, but pygit2 doesn't expose it. It would be very useful if it could.

Any updates regarding this feature? It's been quite a while

Also, how would one go about exposing those methods to pygit2? I didn't find anything that could help me help you on implementing them
