abort: added support for rebase

This adds support of `rebase` to `hg abort` plan.

An independent abort logic for `rebase` is created
under `abortrebase()` function. For this a seperate
`rebaseruntime` object is created under the function to
handle an unfinished `rebasestate` and abort that using
abort logic under `_prepareabortorcontinue`.

Results of tests are shown.
