rebase: extract rebaseset and destination computation in a function
The whole rebase function is gargantuan and this computation is almost 100 lines
long. We extract it in a dedicated function as it is independent from the rest
of the rebase code.
Having it in its own function will make it easier to rework the default
destination logic.
