Function get_worktrees_internal

worktree.c:185–215

* NEEDSWORK: This function exists so that we can look up metadata of a * worktree without trying to access any of its internals like the refdb. It * would be preferable to instead have a corruption-tolerant function for * retrieving worktree metadata that could be used when the worktree is known * to not be in a healthy state, e.g. when creating or repairing it. */
