[cache_repair, thin_repair] fix bug introduced in recent patch
...
I hadn't realised that check_file_exists() also checked that it was
a regular file, which we don't want for the couple of uses I recently
added.
This patch adds an optional arg must_be_regular_file, and defaults
it to true, preserving the original behaviour. The recent additions
have this set to false.

Repair was falling back to non-repair behaviour if it thought the roots

executed.

[thin_repair, thin_dump] Don't look for better roots if the ones in the sb are ok.
...
Calculating the most recent trees is inexact, so trees other than the ones
in the superblock, which presumably are the most recent, could be chosen.

[thin_dump, thin_repair] Fix bad metadata_damage exception
...
The first pass of the repair process scans all metadata working out the
largest orphan btrees. This scan doesn't use as much validation as
the btree_walk function which subsequently gets called.
This patch catches any exceptions thrown by the btree walk function
and removes that btree from consideration.

[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the superblock pointing to very out of date btree roots and so we get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.

boost/optional/optional_io.hpp exists since at least Boost 1.34.0, so it is
safe to include in older versions, too.
