[block_manager] Hard code block size to 4k.
...
We're never going to use anything other than 4k, and by hard coding it we
avoid making block_manager a template.

Corrupt superblock repair

[thin-repair, thin_dump] When repairing we now hunt for the best btree roots.
...
We've had a trickle of users who accidentally activate the same pool on a
VM and host at the same time. Typically the host doesn't do any IO, but
the kernel will still rewrite the superblock on shutdown. This leaves
the superblock pointing to very out of date btree roots and so we get
massive metadata loss.
This patch changes thin_repair, and thin_dump --repair. They now hunt
for the most recent, undamaged and consistent roots of the device and
mapping trees, and use that as the starting point of the repair.
