65264911c1 [thin_repair, thin_dump] --repair falg wasn't being passed through properly.

9e20465fd1 [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the superblock pointing to very out of date btree roots and so we get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.

de7c9a5781 [thin_journal_check] Checks journal of block manager activity. 
You need to apply doc/bm-journal.patch to create the journal.

thin_journal_check confirms that if the machine had crashed at any time
during the test run no metadata corruption would have occured.

1311447a94 [build] Include boost/optional/optional_io.hpp in thin-provisioning/emitter.h (#102) 
This fixes following build failure with Boost 1.67.0:
```

   ^~~~~~~~~~~~~~~~~~~~~~~
make: *** [contrib/Makefile:15: contrib/thin_sexp_emitter.o] Error 1
```

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

b7d418131d Spin-off syscall-related file operations (#78) 
* [file_utils] spin-off syscall-related file operations

1. Eliminate the potential circular dependency between
   persistent-data/block.h and persistent-data/file_utils.h,
   if the former one wants to include the latter.
2. Avoid namespace pollution by removing the "using namespace std"
   declaration in block.tcc.
3. Correct the header hierarchy: base/xml_utils.h now no longer
   depends on the higher-level persistent-data/file_utils.h

* [file_utils] support block files in get_file_length()

2815aeace9 [thin_repair] fix regression in thin_repair 
When opening the corrupted metadata we don't need to touch the space
maps.  This used to be achieved by pretending we were opening a
metadata snap at block 0 (superblock location).  But got changed in
the recent rationalisation of the metadata constructors.

This patch introduces a bool to the metadata OPEN constructor that
says whether the space maps are needed or not.
