Summary: Automatically rebase unstable commits left behind after a split or fold in the middle of a stack. Previously, users had to run `hg restack` to fix their stacks after the fact. This change also fixes the issue identified in t14560234 whereby the old stack (entirely obsolete) stack would be left visible after splitting or folding a head commit due to the inhibit extension not correctly deinhibiting the old stack. Test Plan: Create a stack of commits and perform `hg split` or `hg fold` on a commit (or set of commits) that have descendants. After the operation these commits should be rebased, preserving the linearity of the stack. See unit tests for specific test cases.

does inhibit its descendants in the old stack. The fold command should

manually inhibit any visible obsolete commits in the old stack.
